Basil is most often thought of as an herb for Italian pasta sauce and pesto, but it has so much more to offer. From holy uses and sacred traditions to medicinal, herbal and culinary uses, along with healing tea from its leaves and repelling biting insects, basil has a lot going for it. Add in that it’s extremely easy to grow, and there’s no wonder basil is at the top of the list for must-have herbs for the home gardener and kitchen chef.
Basil is a Mint?
Basil is a member of the mint family, which helps to explain its exuberant and sometimes aggressive growth habit. Combine this with its prolific seed production and ability to easily re-seed itself and you should never be short of basil in your garden.
By some estimates, there are over 150 different species, or cultivars of basil worldwide. The basil plant is characterized by square, branching stems with leaves growing opposite each other from the stem and brown or black seeds in groups of four in pods or nutlets at the top of the plant where the flower spike first blooms.
Ancient Roots
Basil is one of the older herbs cultivated and valued for its aromatic, medicinal and culinary properties. It is commonly thought to have been brought to ancient Greece from Asia by Alexander the Great. From there it spread through seed trade and consumption to India, then on to England by the 1500s, arriving in America by the early 1600s.
Many American gardeners know the herb for its culinary uses and are most familiar with the Italian varieties Sweet and Genovese basil, but there is much more to basil than only these two famous cultivars.
For instance, Thai basil has a similar leaf shape as sweet basil, but packs a more aromatic punch along with a very pleasant and unique anise-like flavor. They are initially a bit sweeter than their Italian cousins before the anise flavor appears, and they hold up to cooking a bit better due to their stronger flavors.
Holy basil or Tulsi originated in India, where it is considered to be one of the most sacred plants in the Hindu religion. In Hindu mythology the plant is an incarnation of the goddess Tulsi. It is used as a medicinal plant for its essential oils and as an herbal tea. It is considered to be an elixir of life, considered to be beneficial for the mind, body and spirit. There are two main types grown in India, a green leafed and a purple leafed cultivar.
Some basil varieties have a strong citrus aroma and flavor, such as the lemon and lime cultivars. Although they both have a citrus scent, they are completely different species. The lemon basil has a high essential oil content, boosting its aromatic properties while the lime cultivar is a bit more subdued in both scent and flavor.
Besides using the leaves in cuisine and as a tea, basil has other traits which make it very valuable for the home gardener.
Due to the aromatic nature, most basils are very effective at warding off biting and annoying insects. Having a planter on the back deck or porch, as well as a bush at the garden entrance allows the passive deterrence as well as being able to pull off a leaf, crush it and rub it on clothes to keep the biters at bay. When the flowers are in bloom, simply pulling the flowers through your hands and inhaling the heavenly aroma works wonders for relaxation and clearing the mind for a few minutes.
Too often, home gardeners think when a basil plant “bolts” or starts setting flowers that it is done for the season. This is not true at all! The flower stalks can simply be pruned at the base of the first flower, re-setting the leaf production mechanism for another round if the weather is still warm enough and the days long enough. Some cultivars, such as the Genovese variety, can be encouraged back into leaf production and give six or even eight harvests of leaves, making for lots of fresh pesto in the freezer to remind us of just exactly what high summer smelled and tasted like during the coldest depths of winter.
It is highly advisable to let a couple of the plants keep their flower stalks as basil is a very strong pollinator attractant, bringing in many different species of
The freshly trimmed flower stalks are excellent when shredded and tossed into salads or among greens on a sandwich, giving a delightful aroma and light, bright flavor. We have also used them in our breakfast eggs and green smoothies for the same effects. Just be aware that a little goes a long way and start with just a couple of flowers so as not to overpower the rest of the dish.

Once enough leaves have been harvested, let the flowers do their work and harvest the seeds as they have several different contributions to make besides just growing new plants next season. Basil seeds don’t readily “shatter” or scatter like sunflowers or other flowers, so it is simple enough to just let the flowers dry down and the seeds mature. To harvest, just snip the stalk at the base of the flower, exactly like pruning the early flowers. It is best to do this just before the flower stalks are completely dry as the seeds can scatter when the stalks are disturbed. Collect the stalks in a tall paper bag and allow them to completely dry for a month or more. Then shake the paper bag side to side and tap the stalks against the inside of the bag to finish freeing the seeds.
The resulting seed is delicately perfumed seed when crushed or ground. Its scent is unlike the parent plant, much more floral and light, but still strong enough to brighten up a room. Use a mortar and pestle or herb grinder to release its magic and use them in muffins, cakes, eggs, pancakes or any dish where a bright floral scent would be an unexpected welcome, especially in the colder seasons.
Making Fresh Tulsi Tea
We really enjoy fresh Tulsi tea in the summertime. We will walk you through just how easy it is to make-
Making Tulsi or Holy Basil tea is very easy. We use a tea brewing pitcher that separates the tea leaves from the brewed tea, but you can use a large tea ball, or simply put the leaves into the water, let steep and strain. Boiling hot water isn’t needed, but warm water will brew faster and extract more of the essential oils than cold.
We like our Tulsi tea a bit stronger, so we gently pack the leaves in, but not too tight or they won’t brew well.
After putting the leaves into the pitcher, adding hot water and closing the top, let the tea brew.
The tea is ready to drink when you think it is – meaning, let your taste be the guide. Some like it much milder than others, so enjoy it your way!
After removing the strainer, the pitcher is the serving and storage container.
Time for some Tulsi tea and a few minutes to sit and relax!

Growing more food from the same garden space seems like a fantasy to many gardeners. Yet, there are a few highly proven, time-honored techniques which have been tested and refined over the past several centuries which are perfect for today’s gardens.
We will show you two of these techniques in today’s article, giving some examples to get you started. Do not be fooled by the simplicity of these approaches, as they are easy and quick to understand but have many nuances that will only show themselves to you with experimenting and careful observation.
Also, don’t be put off thinking these are too difficult to try or to have initial success with. You will be amazed at the increase from your existing garden bed with a first approach, but realize that a careful and thoughtful study will return much more for years to come.
How Succession Planting Works
Enjoying delicious, freshly picked greens from your garden from mid spring through winter, even after the first frosts and into the harder freezes is entirely possible with just a little planning and understanding. The amazing part is it doesn’t much matter what climate you live in. Most greens thrive in cooler weather, but there are some heat loving varieties which will fill in the hotter months.
Spinach is a fast growing cool season green that only lasts a short time, so it needs to be re-planted every couple of weeks for a continual harvest. This is known as succession planting. Lettuce is another cool season crop that can either be harvested continually for leafy types or must be succession planted for the heading varieties of lettuce.
Succession planting involves seeding a short section of a garden bed, letting the crop start to grow then planting the next section a couple of weeks later. This continues down the bed, with the crop maturing in successive waves and giving you a continual harvest. Most gardeners will succession plant only a couple of feet at a time, so as not to overwhelm themselves with too much of a harvest at one time.
Other greens, such as Swiss chard, kale and collard greens grow more slowly and can be harvested all season long – they are both heat and cold tolerant, giving double duty in the garden.
Heat loving greens include amaranth, New Zealand spinach, Huazontle or Red Aztec Spinach and both red and green Malabar spinach, besides the above mentioned types.
Make sure to expand your focus outside of only greens, as there are many other vegetables which will do extremely well in succession planting. One example for a single garden bed or row are a full garden bed planting of early spring peas (which have a harvest season of just a couple weeks) followed by Bok Choi or other Chinese cabbage in a succession pattern, which is then followed by New Zealand spinach going into the warmer weather. This could be extended with fall radishes, beets, Swiss chard or kale if there is enough growing season.
Green onions succeeding summer greens
From this one row, you have gotten three or four different vegetables on an almost continual basis from early spring into very late fall or early winter. If you are able to provide some cold weather protection or season extension for the bed, such as a plastic sheet row cover supported on PVC hoops, you can easily extend that season by a couple of weeks on the spring side and a month on the fall or winter side.
In some climates, just that one simple addition will give you the ability to grow year-round, with spinach, Swiss chard and kale rounding out the slower growing and colder winter.
Another example would be early spring spinach and lettuce, followed by bush snap beans, then fall beets. Or early season carrots can be followed by snap beans during the warmer months with radishes in the fall.
Succession planting on left and intercropping lettuces on right.
These varieties should be planted early – small beets and beet greens, young cabbage, carrots, cauliflower, kohlrabi, lettuce, green onions, peas, radishes, spinach, and turnips; as these are all cool-weather crops. They can be followed by warm-weather crops such as beans, melons, squash and transplants of eggplant, peppers and tomatoes. The warm-weather crops can then be followed by another planting of your favorite cool-weather crops which will mature in the fall.
Any succession can be made that allows crops to reach maturity within the growing season. Swiss chard, Chinese cabbage, collards, corn salad, endive, kale, leeks, lettuce, and mustard are cool-season crops that can follow warm-season crops for late autumn and winter harvest.
What Intercropping Is and How to Use It
Another technique to grow more from the same amount of garden space is called intercropping or interplanting. This makes use of faster maturing varieties planted alongside slower maturing ones. Both are planted at the same time, with the fast growing vegetables being pulled and eaten before they interfere with the slower growing ones. This makes greatly efficient use of a smaller garden space and can double or triple the amount of food grown on the same space.
Quick-maturing crops include: radishes, leaf lettuce, green bunching onions, turnips, and mustard greens. These crops usually mature in 60 days or less from sowing to harvest.
Slower or long-maturing crops include tomatoes, corn, squash, cabbage, eggplant, and peppers. These crops require more than 60 days from sowing until harvest, often 90 days or more.
When planning to intercrop a garden bed, pay particular attention to the days to maturity on the web site and description.
Here is a simple step-by-step guide to succession crop planning:
Make a list of what you want to grow.
Know the number of days in your growing season, which is the approximate number of days between the last usual frost in spring and the first usual frost in fall. If you don’t know this information, refer to the First and Last Frost Dates Tool, and read our Planning and Planting Your Spring Garden article. Determine if the growing season is long enough to grow the crop you have in mind? Is the winter mild enough to over-winter hardy crops with or without weather protection?
Know the number of days to maturity for each variety you plan to grow; both how much time short and long season crops need.
Decide if you need to extend the growing season in spring or fall with weather protection such as cloches, floating row covers, plastic tunnels, or cold frames.
Make a map of the garden beds for the beginning, middle, and end of the growing season: what spaces will be vacant when. Use a separate map for early, middle and late season so you don’t get confused with trying to detail too much on one map.
Start small and be flexible: inexperience, soil and air temperatures, the weather, pests, diseases, and other unforeseen events may alter your plans. It is much easier to try mapping and succession planting one bed this season to get the experience, be successful and enjoy the process than to try all of the beds and get frustrated.
Intercropping has three main advantages compared to only growing one variety at a time in a garden bed. First, this method allows you to squeeze two, three or more beds of vegetables into one, without detriment. Something as simple as a bed of carrots with a trellis of cucumbers down the middle makes a big difference in the amount of food grown. Learn to think vertically as well as width and length of the garden bed.
The second advantage is with a bit of planning, plants can benefit and protect each other. Even passive protection such as a better microclimate under the plant leaf canopy can deter destructive pests. If you plant varieties of vegetables, herbs and flowers which are actively beneficial to each other, then you’ve just stepped everything up a notch!
The third advantage is a dense plant cover or canopy, creating a more beneficial and stable microclimate for the soil and micro-organisms in it. The moisture levels will be more consistent, needing less amount of water less frequently while keeping temperatures more stable, reducing stresses on the plants and their moisture transport systems.
Intercropping kale and Swiss chard in a container.
A word of caution here – plants do not like to be crowded or spaced too closely together to where they begin to compete for resources such as moisture, nutrients or light. Start small and add one crop to this year’s planned garden bed, not trying to squeeze all four in the first season. Once some experience is gained, then add more and in a year or two the garden bed might look like the following!
In his book “The Winter Harvest Handbook”, Eliot Coleman talks about the French market growers around Paris would sow an early spring hotbed with a mixture of radish and carrot seed by broadcasting the seed by hand. Lettuce seedlings would be immediately transplanted into the bed.
The radishes would mature first and be harvested, giving room for the carrots growing between the lettuces. The carrot tops would grow above the young lettuces until the lettuce matured and were harvested, leaving more room for the carrots. Once the lettuce was harvested, cauliflower starts were transplanted into the bed. Once the carrots were harvested, the cauliflower was alone until it was harvested and the bed made ready for the next set of crops.
Using this example, four crops of significant amounts are harvested from one bed during a single season. The bed wasn’t allowed to be idle after that season either, it had a fresh thick layer of well-aged compost applied and worked in, then it was re-seeded with a different mixture of seeds and transplants. Given this example of cool season crops being planted, the next set was probably warm season varieties such as beans, cucumbers, squash, Swiss chard, melons and bunching onions with transplants of tomatoes, peppers and eggplant.
Fall intercropping – tomatoes finishing with cabbage and Brussels sprouts
With all of these positive, productive examples, there are a couple of things to realize at this point.
One, becoming successful at intensive intercropping and succession planting takes some skill and experience. Gaining that skill and experience requires making some mistakes, learning from them and documenting what was planted when in a Garden Journal for future reference.
While the explanation of intensive planting is easy to understand and we’ve shared a number of successful examples, what will ultimately work in your particular garden depends on several factors which are very possibly quite different than ours.
Two, managing a very intensively planted garden will give abundant yields of vegetables but will require more thought, planning and time in the garden initially during planting and again during the harvest when significantly larger amounts of crops are hitting the kitchen counter and dining room table. There will simply be much more food needing attention than before.
This leads to the need for skills and knowledge in preserving the gardens bounty through freezing, canning, dehydrating, fermenting and pickling. Of course, the consequence of this course of action is having much more food on hand and the inescapable sense of accomplishment when the realization strikes that there are several months’ worth of home-grown, delicious food put away.
Perhaps this is how one garden can change the world! Or maybe it should be one garden at a time…

Alpine strawberries have captivated our taste buds for a very long time. They are tiny yet highly aromatic and hugely flavorful ancestors of our common strawberry. Archeological excavations have shown Stone Age people in Denmark and Switzerland enjoyed them immensely, as shown from the evidence of seeds in those sites.
What we would recognize as alpine strawberries were first domestically cultivated in ancient Persia, where they were considered delicacies fit only for royalty. As often happens, seeds made their way both east and west through trade along the Silk Road route, becoming widely grown and loved.
The Roman poet Virgil named the strawberry in works about country life, associating it with other wild fruits and citing the beauties of the fields in his third Ecologue. During the same period Ovid mentions the mountain strawberry in his description of the Golden Age in book one and again in book thirteen of his Metamorphoses narrative. Pliny is considered the last of the ancients to write of the strawberry, listing “Fraga”, the strawberry fruit, as one of the natural products of Italy in the twenty first book of his Natural History series.
From the 10th century until the early 19th, alpine strawberries were hugely profitable, highly regarded and very well known. After suffering from some mis-informed bad publicity in the mid-1100s, alpine strawberries became quite popular in religious paintings beginning in the late 1300s – often associated with Mary and the Baby Jesus in illuminated manuscripts and paintings. The Catholic Church and royal families from Italy, France, England and Germany were responsible for much of the promotion of the alpine strawberry as they tasted and fell in love with it.
Madonna among the Strawberries – with the carpet of alpine strawberries
A few excellent examples are located in the School of Cologne in Germany. “The Madonna of the Roses”, “The Garden of Paradise” and the “Madonna among the Strawberries” all portray the Madonna as a young girl in a closed garden with the infant Jesus in her lap. She is surrounded by roses, thistles, carnations, lily of the valley, iris, primrose and the entire plants of the alpine strawberry, showing its tiny, prolific red fruit and white five petal flowers along with its toothy leaves. The alpine strawberries are painted botanically correct and are exact, perfect replicas of what we see today. They are always portrayed in a place of honor and importance, reflecting the standing they held in elevated society of the day.
By the late 1300s the alpine strawberry was in widespread cultivation throughout Europe as more of the working classes began transplanting the alpine strawberry from the woods and wilderness to their gardens. Street vendors were selling the fruit to Londoners in 1430 when John Lidgate wrote the song “London Lickpenny” which mentions ripe strawberries and cherries for sale in London.
All strawberries up until the mid-1700s were all of the alpine or wood type; being very small, highly aromatic and having much more flavor than would be thought possible for their size. These characteristics are what made them so remarkable, along with their intense sweetness. Another interesting fact is not all of these strawberries were red; there were white and yellow varieties which were just as highly regarded as the red ones, having different flavors of their own.
This begin to change with the world exploration of the early 1700s, with plant and animal samples brought back to Europe from all over the world.
It wasn’t until 30 years later when someone brought back male strawberry plants from Virginia that the Chilean strawberries began to produce fruit, creating the first hybrid strawberry. This new variety is the foundation of all domestic strawberries grown today with the large and familiar heart-shaped fruit.
As would be expected, alpine strawberries began a decline in popularity as their larger sized and heavier producing cousins gained recognition, both in Europe and America.
Alpine strawberries returned to their former, more exclusive roots, being highly valued by pastry and dessert chefs in France and across Europe for their highly concentrated flavors, balanced sweetness and heady aroma that would perfume a room. Eventually, French and Viennese pastry chefs would raise the use of “Fraises des Bois” to a high art form, competing with each other to make the most visually stunning, aromatic and delicious pastries and desserts possible.
Today, alpine strawberries are almost nonexistent in grocery or specialty stores, but are imported from Europe as ingredients in gourmet jams, sauces, liqueurs and as a coloring agent in cosmetics. The best way to experience these flavors and scents – often described as “ambrosia” – for yourself is to grow them in your garden.
While alpine strawberries may not be as productive in weight as their domestic cousins, what they lack in quantity is more than made up for in quality. Given fertile soil, proper conditions and some care, they can be very productive. Enough so that some caterers, confectioners and resorts are buying from local growers specializing in alpine strawberries.
Besides a good quality, fertile and well-drained soil, alpine strawberries need a good amount of sun. In hot areas, they will benefit from partial or afternoon shade. Consistent soil moisture is a key factor in encouraging production, along with a good layer of mulch along their roots to keep them moist. Another benefit is they readily grow true from seed, unlike domestic strawberries which must be started from vegetative propagation.
They don’t send out runners, instead concentrating their energies in flowering and fruiting. They will slowly increase their crowns and gradually grow into mounds about a foot in both diameter and height. They will often flower the first year, but normally won’t set fruit until the second year and will continue producing for several years if well kept. Because of their growth habits, alpine strawberries make for great border plantings as well as edging along a garden walkway or in larger patio containers. They are perennial and can be very cold tolerant if their crowns are heavily mulched to about eight inches before the first hard freeze.
With a little planning and care in planting and tending your plants, you can experience firsthand why mankind has had such an intense love affair with strawberries for so long. You get to taste the same explosion of flavors and be captivated by those intense aromas which Persian kings and European royalty enjoyed so long ago, right there in your home garden.

Papalo is a fabulous, but still relatively unknown, ancient Mexican herb you should be growing. A heat-loving alternative to cilantro, its flavors are both bolder and more complex. It has been described by some as somewhere between arugula, cilantro and rue; others say it tastes like a mixture of nasturtium flowers, lime, and cilantro. Younger leaves are milder flavored, gaining pungency and complexity as they mature.
Papalo (PAH-pa-low) is known by many names; Quilquiña, Yerba Porosa, Killi, Papaloquelite and broadleaf in English. It is a member of the informal quelites (key-LEE-tays), the semi-wild greens rich in vitamins and nutrients that grow among the fields in central and South America. These green edible plants grow without having to plant them. They sprout with the first rains or field irrigation, often providing a second or third harvest, costing no additional work but giving food and nutrition.
Other quelites include lamb’s quarters, amaranth, quinoa, purslane, epazote and Mache or corn salad.
Papalo pre-dates the introduction of cilantro to Mexico by several thousand years, which is a very interesting story all by itself. South America is thought to be the ancestral home of papalo.
Cilantro is also known as Chinese parsley and was brought to Mexico in the 1500s by Chinese workers in the Spanish silver mines of southern Mexico and South America. Spain had a huge trade industry with China, exchanging silver from America for china, porcelain and various drugs – opium and hashish among them. They also imported many Chinese workers for the silver mines, as European diseases had decimated the native population which had no immunity. The Chinese workers brought along foods, herbs and spices which were familiar to them, so cilantro came to the Americas.
Papalo is sometimes called “summer cilantro” due to its heat-loving character and its delay in bolting and setting seed until late summer or early fall.
The name Papalo originates with the Nahuatl word for butterfly, and Papaloquelite is said to mean butterfly leaf. The flowers provide nectar to feeding butterflies, while also attracting bees and other pollinators to the garden with their pollen.
Part of the aroma and flavor is seen above with the oil glands which look like spots on the underside of the leaves. Those glands produce a fragrance which repels insects from eating its leaves.
There are two different leaf shapes grown – a broadleaf and a more narrow leaf, often called poreleaf. We have found the broadleaf variety to be more palatable, quite a bit more pungent than cilantro but quite tasty. When beginning to use papalo, start with 1/4 to 1/3 as much as the normal amount of cilantro. The flavor is much stronger and lasts longer, so a little goes a long way until you’ve gotten used to it. We grow and offer only the broadleaf variety.
When we hear about people complaining of papalo tasting of soap, detergent or having a rank or funky odor, usually they have encountered the poreleaf or narrow leafed variety. It is quite a bit more pungent than the broadleaf type, so usually comes as quite a shock to our palates.
Papalo seeds look much like dandelion seeds, with the stalk and “umbrella” to help carry them on the wind to their new home. Having the umbrella attached is very important to good seed germination, which we will show you in just a bit.
The harvested seed comes from our grower in a big clear plastic trash bag, as it just isn’t possible to harvest and clean the seeds without breaking the umbrellas off. The seeds are almost weightless, so a big bagful that you can hide behind weighs less than a pound.
Cindy has a handful of seed heads, showing how they clump together after maturing. As the seed matures, the sheath or covering that protects the young seeds peels back, exposing these clusters to the wind, which will carry them away as they dry.
A closer look at the clump of seeds. We haven’t found a better way to separate them without damaging them, so we usually pack them much like this – by the ever so gentle pinch! There are probably 30+ seeds in this photo.
Papalo is often described as having “very low and variable” germination. This is true if the seed is packed in a standard seed packet, which breaks off the umbrella from the stem. From experimenting, we have found germination will drop to around 10% if the seed is broken, but will be as high as 90% or better if the seed is intact.
This photo of papalo in our germination tray shows the proof. Using seed germination paper to keep the seed damp, there was 100% germination in less than 72 hours. In fact, the seedlings hit the lid of the germination chamber, trying to get to the light.
A close-up shows how the stem emerges from the bottom of the stalk, immediately turning vertical in growth, searching for light.
Seen in Cindy’s hand it is easier to identify the parts of the seed and where the seedling emerges from, as well as how tall they can grow in a short time.
We have developed this simple but highly effective packing box from our germination experiments. It keeps the seeds intact for planting as well as protecting them from being broken during shipping.
Young seedlings don’t have the oil glands developed yet, so they are milder in flavor and aroma than when they begin to mature. This planting is a bit thick, but it is sometimes difficult to separate the seeds without damage. In this case, just plant them thick and don’t worry about it. If desired, you can clip the unwanted or unneeded seedlings to thin them. Make sure not to pull them out, as this really disturbs the roots of the adjacent plants and seriously disrupts their growth.
Even in a very harsh spring with sustained high temperatures and punishing winds, the young papalo grows strongly. The weather effects can be seen in the drying of the leaf margins, as well as the scruffy and dry leaf appearance. The holes are not from a bug chewing on the leaves, but from the oil vaporizing from the porous oil glands. The lighter colored spots on the leaves are additional oil glands.
A fully mature papalo leaf in good growing conditions looks like this – a moderately deep, rich green with oil glands distributed across each leaf. The leaves have a medium thickness to them with a fairly substantial feel. They don’t feel delicate like some vegetable leaves, but aren’t thick and succulent either.
Touching them will release some of the aromatic oils, so you should be able to immediately experience their singularly unique aroma, even from an arm’s length away. This is the same with organically grown or home-grown cilantro – the aroma will be much more pronounced.
The seed heads start out looking much like marigold flower heads. After flowering, they will set seed and begin the cycle anew. When harvesting seeds to save, make sure to clip the seed head after it has fully matured and begun to dry but before it is completely dry. Otherwise, you will go out to the garden to collect seeds to find it has all blown away!
In October 1999, when Alice Waters, renowned chef of Chez Panisse in Berkeley, California, first tasted one variety of papaloquelite, she was ecstatic and demanded to know why she had never experienced it before. She purchased every seed packet available from the Underwood Gardens booth at the Taste of the Midwest Festival, an annual event sponsored by the American Institute of Wine and Food.
When we met Alice at Slow Food Terra Madre in Turin, Italy, in 2012, we mentioned this past connection. She immediately remembered the event, and her eyes lit up when we discussed the aromatic flavors and how she introduced them to her restaurant patrons.
It’s always used raw and added at the last minute, giving its signature, unique piquant flavor to dishes. It’s used in fish dishes, salsas and guacamole. There is a memorable guacamole that uses cucumbers and papalo for added depth of flavor that we can’t get enough of. We also really like it in scrambled eggs, fresh salsas, and finely diced in a strongly flavored salad of spinach, arugula, mustard greens, and kale. Devilled eggs take on an entirely new dimension with a couple of leaves finely diced and mixed into the filling. People always try to guess the mystery seasoning and always mistake it for something else.
In restaurants in the state of Puebla in Mexico, it’s common to find a sprig of papalo in a glass jar of water on the table, next to the salt, pepper and salsas — ready to be added raw to soups, tacos, tortas or beans. The diners will take off a leaf or two and tear it up finely before sprinkling it over their meal.
Papalo is very easy to grow and has a history stretching back thousands of years, so give it a try in your herb garden this season!
Achocha or Caihua (pronounced kai-wa) is an unusual and relatively unknown member of the cucurbit or cucumber family with a difference. Although they share family roots with cucumbers, squash, pumpkin, zucchini and melons, they arealmost completely immune to many of the diseases and pests that attack the other cucurbits – squash bugs, vine borers, cucumber worms and powdery mildew along with other fungal issues.
Achochaare hugely prolific both in leafy shade growth and fruit, making them a dual purpose plant for gardeners looking for a green shade or windbreak which gives a good supply of tasty food.
Originally domesticated in the Andes Mountains, the seeds travelled by trade from modern day Columbia in the north to Bolivia in the south. This ancient crop has been featured on pre-historic pottery and art and is discussedin the book “Lost Crops of the Incas” by the National Research Council. Today, they are widely grown all across Central and South America, as well as in many other parts of the world. For example, achocha is very popular in northern India, Nepal and Bhutan.
The seeds are very intriguing, looking much like flecks of bark or burnt chunks of a rough plant material. The color ranges from a medium brown to an almost black. Each mature fruit will have several seeds in it.
A close-up of the seeds shows how very different they appear from almost all other vegetables, and certainly other cucurbit family seeds.
Another look at the achocha seed. The majority of them have the little tail or protrusion seen here.
Achocha puts on vigorous vine growth with lots of leaves which provide a good shade for other crops. In areas with a long hot season, establishing them early will give better growth as they slow down during the hottest times. Giving them a bit of afternoon shade and protection helps them along, as they are seen growing up through a patch of Butter Daisies and climbing up a trellis.
This is a western facing wall, and they had a bit of a challenge in becoming well established with the afternoon heat. They had morning shade, but were exposed to full sun and heat during the hottest part of the day until almost sundown.
On the opposite side of the wide walkway, they are seen much more established and prolific. This is the east facing wall that is shaded from early afternoon, giving the plants enough protection from high heat and constant sun exposure to really take off.
This was the most productive planting, giving handfuls of fruit each harvest.
Cindy is holding a young fruit with the blossom cap still attached. At this stage the bark-like seeds are still fairly soft and immature. The fruit will not have completely hollowed out yet, but it is very edible and mild in flavor with a soft texture.
Once the plants begin setting fruit, they should be harvested regularly to encourage continued production. As they begin to produce, you will have handfuls of the fruit to work with!
The tiny, off-white flowers can be seen in the background. It is best to plant at least two plants so they can pollinate each other. The flowers will attract a number of smaller insects to help with pollination, among them the beneficial serphid fly which feasts on aphids, thrips and other soft bodied destructive insect pests.
Another view of the size, shape and color of the achocha fruits, along with the foliage. There are a few different varieties of achocha – some with soft spines and a fatter fruit. Ours are more slender and smooth skinned with no soft spines.
The foliage will sometime raise eyebrows and cause questions, as its long toothy leaves somewhat resemble another controversial plant. There is no relation, but it is a conversation starter!
One handful of fruit leads to discovering another, then another as well…
Very colorful, unique and eye-catching along with being delicious, they will be the center point of the table.
In Central and South America the fruits are eaten either raw or cooked after removal of the seeds. They are also prepared as stuffed peppers; stuffed with meat, fish or cheese and then baked or fresh.
Kids often love to pick and eat them in the garden, and they make an excellent addition to salads. The tender shoots, tendrils and young vines are edible and eaten raw or very lightly cooked.
A growing bed can be made from many materials, but when you factor in the ability to make a growing bed from recycled components, then the opportunities become almost limitless. It makes sense in so many ways to make your raised beds from an already-used materials. You will often save a significant amount of money while contributing less to the growing landfills. In addition, you reduce the amount of raw resources used to make new building materials. Often you will find your options are much broader when looking at recycled stock, as the solution can more easily present itself when your mind is more open and relaxed, without a fixed design idea.
This is exactly what led to our finding and choosing this particular metal from our local salvage yard. We know we needed a structurally sound, ecologically friendly and long lasting substance for our raised beds in our garden. The pricing on new lumber which could be in contact with soil for long periods of time was not realistic for the amount of beds we needed to make. One by one, every other reasonably available construction material and method fell out as being much too costly, much too labor intensive or not suitable for our climate.
All of this led us to our local salvage yard. When we let the person know what we were looking to do, he immediately pointed us in the direction of some large-scale roofing they had recently recovered. After looking at a couple of different options, we came across these 3 foot wide and 20 foot long sections of really heavy galvanized steel with most of their avocado green paint still attached. They were heavy enough that it was hard to turn one section over to look at the other side.
When we turned a smaller section over and saw how well it dove-tailed into the long section, we knew we had a custom-made solution to our raised beds. All at a price that was pennies on the dollar of other solutions we had looked at, with a much longer lifespan as a bonus.
We have now used these as raised beds in our garden for almost a decade, with no problems. We recently moved the two smaller beds in our greenhouse and discovered photos of when we made the beds initially and wanted to share the process with you.
Please use this as a guiding hand, suggesting what can be done; don’t go out and expect to find this exact material waiting for you. If you go with an open mind, you just might be surprised at just how well what you find works in your particular garden!
The project started out with our finding some really heavy duty galvanized steel corrugated roofing at our local salvage yard. We then rented an electric nibbler tool to split them lengthwise, as they were too wide or deep to use by themselves.
This is the pile after getting it home, splitting it on the flatbed trailer and then unloading them. A full day’s work!
The unusually large corrugations worked perfectly for us, as we flipped the ends over so they would mate with the sides, creating interlocking tabs. The material is heavy enough for us to just screw together, without needing extra supporting material.
The outside view shows the middle tab already cut, bent over and screwed together. These are strong enough to stand on the top of the sides, once the box is constructed!
Using a Sawzall – an electric reciprocating saw – the tabs are cut. There are top and bottom screws in addition to the middle ones.
After cutting, they are bent over into the channel to be screwed together, making a very strong joint or connection.
A close-up look at the finished middle tab. We used self-tapping screws to eliminate the need to drill a starter hole.
Another feature of the unique corrugations is the channel in the bottom of the side panels which perfectly fits a ¾ inch sheet of marine grade plywood that had been previously waterproofed and drainage holes drilled. After installing the plywood and securing it into the channels, we added a heat cable and hardware cloth on top to protect it from damage from gardening tools. The heating cable is desigened and made specifically for this use and is waterproof with an internal thermostat which shuts off at 70°F.
You can see the channels in the steel in the second and third photos from the top.
For the first few years, we used the bottom heated growing bed in our greenhouse. We made two of them and grew cool season salad greens during the fall, through the winter and into the following spring in the unheated greenhouse.
We used overstock cinder blocks from the local block maker to support the beds.
After installing the beds on the cinder blocks, we put in a bottom layer of sand about two inches deep. The sand keeps the heating cable out of contact with decomposing soil and provides a better heat transfer to the soil on top when the moisture seeps down.
Both growing beds were very successful in growing lots of greens throughout the winter. We often found we couldn’t keep up with all of the greens from just one bed!
The greenhouse is being updated and changed a bit to a grow room, with a solid roof as it gets way too hot in the spring and summer to grow anything, so the growing beds needed to be moved to be more useful and functional.
We experimented with a very simple container garden just off of our back deck last year – with great success. It was very close and convenient for fresh herbs and often used fresh greens – just a step out the back door! The containers were all recycled plastic – from old horse water tubs to industrial food shipping barrels cut in half. They were simply put on top of a base of cinder blocks three high for less bending and ease of gardening. Everything was arranged in a “U” shape, with access to standing on all sides.
They worked very well, so we expanded the container gardening space with adding the two growing beds on each long side of the “U”.
The slightly shorter growing bed is next to an old 100 gallon horse water tub, containing garlic chives and I’itoi onions, both acting as perennials in our climate. This photo is from the very beginning of March, after a cold and wet winter that turned warm in early spring.
Here’s a look at the updated container garden, just after moving the second growing bed. The two large plastic containers in the foreground were what we used last season and were moved to make room for the larger growing bed.

Heirloom Basil – So Much More Than Pesto
Basil is most often thought of as an herb for Italian pasta sauce and pesto, but it has so much more to offer. From holy uses and sacred traditions to medicinal, herbal and culinary uses, along with healing tea from its leaves and repelling biting insects, basil has a lot going for it. Add in that it’s extremely easy to grow, and there’s no wonder basil is at the top of the list for must-have herbs for the home gardener and kitchen chef.
Basil is a Mint?
Basil is a member of the mint family, which helps to explain its exuberant and sometimes aggressive growth habit. Combine this with its prolific seed production and ability to easily re-seed itself and you should never be short of basil in your garden.
By some estimates, there are over 150 different species, or cultivars of basil worldwide. The basil plant is characterized by square, branching stems with leaves growing opposite each other from the stem and brown or black seeds in groups of four in pods or nutlets at the top of the plant where the flower spike first blooms.
Ancient Roots
Basil is one of the older herbs cultivated and valued for its aromatic, medicinal and culinary properties. It is commonly thought to have been brought to ancient Greece from Asia by Alexander the Great. From there it spread through seed trade and consumption to India, then on to England by the 1500s, arriving in America by the early 1600s.
Many American gardeners know the herb for its culinary uses and are most familiar with the Italian varieties Sweet and Genovese basil, but there is much more to basil than only these two famous cultivars.
A Few Varieties to Try
Thai Basil
For instance, Thai basil has a similar leaf shape as sweet basil, but packs a more aromatic punch along with a very pleasant and unique anise-like flavor. They are initially a bit sweeter than their Italian cousins before the anise flavor appears, and they hold up to cooking a bit better due to their stronger flavors.
Holy Basil
Holy basil or Tulsi originated in India, where it is considered to be one of the most sacred plants in the Hindu religion. In Hindu mythology the plant is an incarnation of the goddess Tulsi. It is used as a medicinal plant for its essential oils and as an herbal tea. It is considered to be an elixir of life, considered to be beneficial for the mind, body and spirit. There are two main types grown in India, a green leafed and a purple leafed cultivar.
Genovese Basil on left and Lemon Basil on right
Some basil varieties have a strong citrus aroma and flavor, such as the lemon and lime cultivars. Although they both have a citrus scent, they are completely different species. The lemon basil has a high essential oil content, boosting its aromatic properties while the lime cultivar is a bit more subdued in both scent and flavor.
More Benefits of Basil
Besides using the leaves in cuisine and as a tea, basil has other traits which make it very valuable for the home gardener.
Due to the aromatic nature, most basils are very effective at warding off biting and annoying insects. Having a planter on the back deck or porch, as well as a bush at the garden entrance allows the passive deterrence as well as being able to pull off a leaf, crush it and rub it on clothes to keep the biters at bay. When the flowers are in bloom, simply pulling the flowers through your hands and inhaling the heavenly aroma works wonders for relaxation and clearing the mind for a few minutes.
Too often, home gardeners think when a basil plant “bolts” or starts setting flowers that it is done for the season. This is not true at all! The flower stalks can simply be pruned at the base of the first flower, re-setting the leaf production mechanism for another round if the weather is still warm enough and the days long enough. Some cultivars, such as the Genovese variety, can be encouraged back into leaf production and give six or even eight harvests of leaves, making for lots of fresh pesto in the freezer to remind us of just exactly what high summer smelled and tasted like during the coldest depths of winter.
It is highly advisable to let a couple of the plants keep their flower stalks as basil is a very strong pollinator attractant, bringing in many different species of
The freshly trimmed flower stalks are excellent when shredded and tossed into salads or among greens on a sandwich, giving a delightful aroma and light, bright flavor. We have also used them in our breakfast eggs and green smoothies for the same effects. Just be aware that a little goes a long way and start with just a couple of flowers so as not to overpower the rest of the dish.
Holy Basil seed on left, Genovese basil seed on right
Once enough leaves have been harvested, let the flowers do their work and harvest the seeds as they have several different contributions to make besides just growing new plants next season. Basil seeds don’t readily “shatter” or scatter like sunflowers or other flowers, so it is simple enough to just let the flowers dry down and the seeds mature. To harvest, just snip the stalk at the base of the flower, exactly like pruning the early flowers. It is best to do this just before the flower stalks are completely dry as the seeds can scatter when the stalks are disturbed. Collect the stalks in a tall paper bag and allow them to completely dry for a month or more. Then shake the paper bag side to side and tap the stalks against the inside of the bag to finish freeing the seeds.
The resulting seed is delicately perfumed seed when crushed or ground. Its scent is unlike the parent plant, much more floral and light, but still strong enough to brighten up a room. Use a mortar and pestle or herb grinder to release its magic and use them in muffins, cakes, eggs, pancakes or any dish where a bright floral scent would be an unexpected welcome, especially in the colder seasons.
Making Fresh Tulsi Tea
We really enjoy fresh Tulsi tea in the summertime. We will walk you through just how easy it is to make-
Making Tulsi or Holy Basil tea is very easy. We use a tea brewing pitcher that separates the tea leaves from the brewed tea, but you can use a large tea ball, or simply put the leaves into the water, let steep and strain. Boiling hot water isn’t needed, but warm water will brew faster and extract more of the essential oils than cold.
We like our Tulsi tea a bit stronger, so we gently pack the leaves in, but not too tight or they won’t brew well.
After putting the leaves into the pitcher, adding hot water and closing the top, let the tea brew.
The tea is ready to drink when you think it is – meaning, let your taste be the guide. Some like it much milder than others, so enjoy it your way!
After removing the strainer, the pitcher is the serving and storage container.
Time for some Tulsi tea and a few minutes to sit and relax!
How to Grow More from Your Same Garden Space
Succession Planting and Intercropping Techniques
Growing more food from the same garden space seems like a fantasy to many gardeners. Yet, there are a few highly proven, time-honored techniques which have been tested and refined over the past several centuries which are perfect for today’s gardens.
We will show you two of these techniques in today’s article, giving some examples to get you started. Do not be fooled by the simplicity of these approaches, as they are easy and quick to understand but have many nuances that will only show themselves to you with experimenting and careful observation.
Also, don’t be put off thinking these are too difficult to try or to have initial success with. You will be amazed at the increase from your existing garden bed with a first approach, but realize that a careful and thoughtful study will return much more for years to come.
How Succession Planting Works
Enjoying delicious, freshly picked greens from your garden from mid spring through winter, even after the first frosts and into the harder freezes is entirely possible with just a little planning and understanding. The amazing part is it doesn’t much matter what climate you live in. Most greens thrive in cooler weather, but there are some heat loving varieties which will fill in the hotter months.
Spinach is a fast growing cool season green that only lasts a short time, so it needs to be re-planted every couple of weeks for a continual harvest. This is known as succession planting. Lettuce is another cool season crop that can either be harvested continually for leafy types or must be succession planted for the heading varieties of lettuce.
Large Container Succession Planting
Succession planting involves seeding a short section of a garden bed, letting the crop start to grow then planting the next section a couple of weeks later. This continues down the bed, with the crop maturing in successive waves and giving you a continual harvest. Most gardeners will succession plant only a couple of feet at a time, so as not to overwhelm themselves with too much of a harvest at one time.
Other greens, such as Swiss chard, kale and collard greens grow more slowly and can be harvested all season long – they are both heat and cold tolerant, giving double duty in the garden.
Heat loving greens include amaranth, New Zealand spinach, Huazontle or Red Aztec Spinach and both red and green Malabar spinach, besides the above mentioned types.
Make sure to expand your focus outside of only greens, as there are many other vegetables which will do extremely well in succession planting. One example for a single garden bed or row are a full garden bed planting of early spring peas (which have a harvest season of just a couple weeks) followed by Bok Choi or other Chinese cabbage in a succession pattern, which is then followed by New Zealand spinach going into the warmer weather. This could be extended with fall radishes, beets, Swiss chard or kale if there is enough growing season.
Green onions succeeding summer greens
From this one row, you have gotten three or four different vegetables on an almost continual basis from early spring into very late fall or early winter. If you are able to provide some cold weather protection or season extension for the bed, such as a plastic sheet row cover supported on PVC hoops, you can easily extend that season by a couple of weeks on the spring side and a month on the fall or winter side.
In some climates, just that one simple addition will give you the ability to grow year-round, with spinach, Swiss chard and kale rounding out the slower growing and colder winter.
Another example would be early spring spinach and lettuce, followed by bush snap beans, then fall beets. Or early season carrots can be followed by snap beans during the warmer months with radishes in the fall.
Succession planting on left and intercropping lettuces on right.
These varieties should be planted early – small beets and beet greens, young cabbage, carrots, cauliflower, kohlrabi, lettuce, green onions, peas, radishes, spinach, and turnips; as these are all cool-weather crops. They can be followed by warm-weather crops such as beans, melons, squash and transplants of eggplant, peppers and tomatoes. The warm-weather crops can then be followed by another planting of your favorite cool-weather crops which will mature in the fall.
Any succession can be made that allows crops to reach maturity within the growing season. Swiss chard, Chinese cabbage, collards, corn salad, endive, kale, leeks, lettuce, and mustard are cool-season crops that can follow warm-season crops for late autumn and winter harvest.
What Intercropping Is and How to Use It
Another technique to grow more from the same amount of garden space is called intercropping or interplanting. This makes use of faster maturing varieties planted alongside slower maturing ones. Both are planted at the same time, with the fast growing vegetables being pulled and eaten before they interfere with the slower growing ones. This makes greatly efficient use of a smaller garden space and can double or triple the amount of food grown on the same space.
Quick-maturing crops include: radishes, leaf lettuce, green bunching onions, turnips, and mustard greens. These crops usually mature in 60 days or less from sowing to harvest.
Slower or long-maturing crops include tomatoes, corn, squash, cabbage, eggplant, and peppers. These crops require more than 60 days from sowing until harvest, often 90 days or more.
When planning to intercrop a garden bed, pay particular attention to the days to maturity on the web site and description.
Here is a simple step-by-step guide to succession crop planning:
Intercropping has three main advantages compared to only growing one variety at a time in a garden bed. First, this method allows you to squeeze two, three or more beds of vegetables into one, without detriment. Something as simple as a bed of carrots with a trellis of cucumbers down the middle makes a big difference in the amount of food grown. Learn to think vertically as well as width and length of the garden bed.
The second advantage is with a bit of planning, plants can benefit and protect each other. Even passive protection such as a better microclimate under the plant leaf canopy can deter destructive pests. If you plant varieties of vegetables, herbs and flowers which are actively beneficial to each other, then you’ve just stepped everything up a notch!
The third advantage is a dense plant cover or canopy, creating a more beneficial and stable microclimate for the soil and micro-organisms in it. The moisture levels will be more consistent, needing less amount of water less frequently while keeping temperatures more stable, reducing stresses on the plants and their moisture transport systems.
Intercropping kale and Swiss chard in a container.
A word of caution here – plants do not like to be crowded or spaced too closely together to where they begin to compete for resources such as moisture, nutrients or light. Start small and add one crop to this year’s planned garden bed, not trying to squeeze all four in the first season. Once some experience is gained, then add more and in a year or two the garden bed might look like the following!
In his book “The Winter Harvest Handbook”, Eliot Coleman talks about the French market growers around Paris would sow an early spring hotbed with a mixture of radish and carrot seed by broadcasting the seed by hand. Lettuce seedlings would be immediately transplanted into the bed.
The radishes would mature first and be harvested, giving room for the carrots growing between the lettuces. The carrot tops would grow above the young lettuces until the lettuce matured and were harvested, leaving more room for the carrots. Once the lettuce was harvested, cauliflower starts were transplanted into the bed. Once the carrots were harvested, the cauliflower was alone until it was harvested and the bed made ready for the next set of crops.
Using this example, four crops of significant amounts are harvested from one bed during a single season. The bed wasn’t allowed to be idle after that season either, it had a fresh thick layer of well-aged compost applied and worked in, then it was re-seeded with a different mixture of seeds and transplants. Given this example of cool season crops being planted, the next set was probably warm season varieties such as beans, cucumbers, squash, Swiss chard, melons and bunching onions with transplants of tomatoes, peppers and eggplant.
Fall intercropping – tomatoes finishing with cabbage and Brussels sprouts
With all of these positive, productive examples, there are a couple of things to realize at this point.
One, becoming successful at intensive intercropping and succession planting takes some skill and experience. Gaining that skill and experience requires making some mistakes, learning from them and documenting what was planted when in a Garden Journal for future reference.
While the explanation of intensive planting is easy to understand and we’ve shared a number of successful examples, what will ultimately work in your particular garden depends on several factors which are very possibly quite different than ours.
Two, managing a very intensively planted garden will give abundant yields of vegetables but will require more thought, planning and time in the garden initially during planting and again during the harvest when significantly larger amounts of crops are hitting the kitchen counter and dining room table. There will simply be much more food needing attention than before.
This leads to the need for skills and knowledge in preserving the gardens bounty through freezing, canning, dehydrating, fermenting and pickling. Of course, the consequence of this course of action is having much more food on hand and the inescapable sense of accomplishment when the realization strikes that there are several months’ worth of home-grown, delicious food put away.
Perhaps this is how one garden can change the world! Or maybe it should be one garden at a time…
Alpine Strawberries have a Sweet History
Alpine strawberries have captivated our taste buds for a very long time. They are tiny yet highly aromatic and hugely flavorful ancestors of our common strawberry. Archeological excavations have shown Stone Age people in Denmark and Switzerland enjoyed them immensely, as shown from the evidence of seeds in those sites.
What we would recognize as alpine strawberries were first domestically cultivated in ancient Persia, where they were considered delicacies fit only for royalty. As often happens, seeds made their way both east and west through trade along the Silk Road route, becoming widely grown and loved.
From the 10th century until the early 19th, alpine strawberries were hugely profitable, highly regarded and very well known. After suffering from some mis-informed bad publicity in the mid-1100s, alpine strawberries became quite popular in religious paintings beginning in the late 1300s – often associated with Mary and the Baby Jesus in illuminated manuscripts and paintings. The Catholic Church and royal families from Italy, France, England and Germany were responsible for much of the promotion of the alpine strawberry as they tasted and fell in love with it.
Madonna among the Strawberries – with the carpet of alpine strawberries
A few excellent examples are located in the School of Cologne in Germany. “The Madonna of the Roses”, “The Garden of Paradise” and the “Madonna among the Strawberries” all portray the Madonna as a young girl in a closed garden with the infant Jesus in her lap. She is surrounded by roses, thistles, carnations, lily of the valley, iris, primrose and the entire plants of the alpine strawberry, showing its tiny, prolific red fruit and white five petal flowers along with its toothy leaves. The alpine strawberries are painted botanically correct and are exact, perfect replicas of what we see today. They are always portrayed in a place of honor and importance, reflecting the standing they held in elevated society of the day.
By the late 1300s the alpine strawberry was in widespread cultivation throughout Europe as more of the working classes began transplanting the alpine strawberry from the woods and wilderness to their gardens. Street vendors were selling the fruit to Londoners in 1430 when John Lidgate wrote the song “London Lickpenny” which mentions ripe strawberries and cherries for sale in London.
All strawberries up until the mid-1700s were all of the alpine or wood type; being very small, highly aromatic and having much more flavor than would be thought possible for their size. These characteristics are what made them so remarkable, along with their intense sweetness. Another interesting fact is not all of these strawberries were red; there were white and yellow varieties which were just as highly regarded as the red ones, having different flavors of their own.
This begin to change with the world exploration of the early 1700s, with plant and animal samples brought back to Europe from all over the world.
The modern domesticated large fruited strawberry got its start from these collecting expeditions, with a few strawberry plants brought back from a mapping trip to Chile by Amédée-François Frézier, a French naval engineer who noticed and enjoyed the tremendously large strawberries growing along the Chilean coast in 1712. He wrote the fruit were commonly as large as a walnut; almost three times the size of the alpine strawberry of the day. He brought back plants which were installed in the royal gardens and in Brittany, which grew well but did not set any fruit. It was later discovered the Chilean strawberries have male and female plants, and Frézier had only brought back female plants.
As would be expected, alpine strawberries began a decline in popularity as their larger sized and heavier producing cousins gained recognition, both in Europe and America.
Alpine strawberries returned to their former, more exclusive roots, being highly valued by pastry and dessert chefs in France and across Europe for their highly concentrated flavors, balanced sweetness and heady aroma that would perfume a room. Eventually, French and Viennese pastry chefs would raise the use of “Fraises des Bois” to a high art form, competing with each other to make the most visually stunning, aromatic and delicious pastries and desserts possible.
While alpine strawberries may not be as productive in weight as their domestic cousins, what they lack in quantity is more than made up for in quality. Given fertile soil, proper conditions and some care, they can be very productive. Enough so that some caterers, confectioners and resorts are buying from local growers specializing in alpine strawberries.
They don’t send out runners, instead concentrating their energies in flowering and fruiting. They will slowly increase their crowns and gradually grow into mounds about a foot in both diameter and height. They will often flower the first year, but normally won’t set fruit until the second year and will continue producing for several years if well kept. Because of their growth habits, alpine strawberries make for great border plantings as well as edging along a garden walkway or in larger patio containers. They are perennial and can be very cold tolerant if their crowns are heavily mulched to about eight inches before the first hard freeze.
With a little planning and care in planting and tending your plants, you can experience firsthand why mankind has had such an intense love affair with strawberries for so long. You get to taste the same explosion of flavors and be captivated by those intense aromas which Persian kings and European royalty enjoyed so long ago, right there in your home garden.
Papalo – Heat Loving Cilantro Alternative
Papalo is a fabulous, but still relatively unknown, ancient Mexican herb you should be growing. A heat-loving alternative to cilantro, its flavors are both bolder and more complex. It has been described by some as somewhere between arugula, cilantro and rue; others say it tastes like a mixture of nasturtium flowers, lime, and cilantro. Younger leaves are milder flavored, gaining pungency and complexity as they mature.
Papalo (PAH-pa-low) is known by many names; Quilquiña, Yerba Porosa, Killi, Papaloquelite and broadleaf in English. It is a member of the informal quelites (key-LEE-tays), the semi-wild greens rich in vitamins and nutrients that grow among the fields in central and South America. These green edible plants grow without having to plant them. They sprout with the first rains or field irrigation, often providing a second or third harvest, costing no additional work but giving food and nutrition.
Other quelites include lamb’s quarters, amaranth, quinoa, purslane, epazote and Mache or corn salad.
Papalo pre-dates the introduction of cilantro to Mexico by several thousand years, which is a very interesting story all by itself. South America is thought to be the ancestral home of papalo.
Cilantro is also known as Chinese parsley and was brought to Mexico in the 1500s by Chinese workers in the Spanish silver mines of southern Mexico and South America. Spain had a huge trade industry with China, exchanging silver from America for china, porcelain and various drugs – opium and hashish among them. They also imported many Chinese workers for the silver mines, as European diseases had decimated the native population which had no immunity. The Chinese workers brought along foods, herbs and spices which were familiar to them, so cilantro came to the Americas.
Papalo is sometimes called “summer cilantro” due to its heat-loving character and its delay in bolting and setting seed until late summer or early fall.
The name Papalo originates with the Nahuatl word for butterfly, and Papaloquelite is said to mean butterfly leaf. The flowers provide nectar to feeding butterflies, while also attracting bees and other pollinators to the garden with their pollen.
Part of the aroma and flavor is seen above with the oil glands which look like spots on the underside of the leaves. Those glands produce a fragrance which repels insects from eating its leaves.
There are two different leaf shapes grown – a broadleaf and a more narrow leaf, often called poreleaf. We have found the broadleaf variety to be more palatable, quite a bit more pungent than cilantro but quite tasty. When beginning to use papalo, start with 1/4 to 1/3 as much as the normal amount of cilantro. The flavor is much stronger and lasts longer, so a little goes a long way until you’ve gotten used to it. We grow and offer only the broadleaf variety.
When we hear about people complaining of papalo tasting of soap, detergent or having a rank or funky odor, usually they have encountered the poreleaf or narrow leafed variety. It is quite a bit more pungent than the broadleaf type, so usually comes as quite a shock to our palates.
Papalo seeds look much like dandelion seeds, with the stalk and “umbrella” to help carry them on the wind to their new home. Having the umbrella attached is very important to good seed germination, which we will show you in just a bit.
The harvested seed comes from our grower in a big clear plastic trash bag, as it just isn’t possible to harvest and clean the seeds without breaking the umbrellas off. The seeds are almost weightless, so a big bagful that you can hide behind weighs less than a pound.
Cindy has a handful of seed heads, showing how they clump together after maturing. As the seed matures, the sheath or covering that protects the young seeds peels back, exposing these clusters to the wind, which will carry them away as they dry.
A closer look at the clump of seeds. We haven’t found a better way to separate them without damaging them, so we usually pack them much like this – by the ever so gentle pinch! There are probably 30+ seeds in this photo.
Papalo is often described as having “very low and variable” germination. This is true if the seed is packed in a standard seed packet, which breaks off the umbrella from the stem. From experimenting, we have found germination will drop to around 10% if the seed is broken, but will be as high as 90% or better if the seed is intact.
This photo of papalo in our germination tray shows the proof. Using seed germination paper to keep the seed damp, there was 100% germination in less than 72 hours. In fact, the seedlings hit the lid of the germination chamber, trying to get to the light.
A close-up shows how the stem emerges from the bottom of the stalk, immediately turning vertical in growth, searching for light.
Seen in Cindy’s hand it is easier to identify the parts of the seed and where the seedling emerges from, as well as how tall they can grow in a short time.
We have developed this simple but highly effective packing box from our germination experiments. It keeps the seeds intact for planting as well as protecting them from being broken during shipping.
Young seedlings don’t have the oil glands developed yet, so they are milder in flavor and aroma than when they begin to mature. This planting is a bit thick, but it is sometimes difficult to separate the seeds without damage. In this case, just plant them thick and don’t worry about it. If desired, you can clip the unwanted or unneeded seedlings to thin them. Make sure not to pull them out, as this really disturbs the roots of the adjacent plants and seriously disrupts their growth.
Even in a very harsh spring with sustained high temperatures and punishing winds, the young papalo grows strongly. The weather effects can be seen in the drying of the leaf margins, as well as the scruffy and dry leaf appearance. The holes are not from a bug chewing on the leaves, but from the oil vaporizing from the porous oil glands. The lighter colored spots on the leaves are additional oil glands.
A fully mature papalo leaf in good growing conditions looks like this – a moderately deep, rich green with oil glands distributed across each leaf. The leaves have a medium thickness to them with a fairly substantial feel. They don’t feel delicate like some vegetable leaves, but aren’t thick and succulent either.
Touching them will release some of the aromatic oils, so you should be able to immediately experience their singularly unique aroma, even from an arm’s length away. This is the same with organically grown or home-grown cilantro – the aroma will be much more pronounced.
The seed heads start out looking much like marigold flower heads. After flowering, they will set seed and begin the cycle anew. When harvesting seeds to save, make sure to clip the seed head after it has fully matured and begun to dry but before it is completely dry. Otherwise, you will go out to the garden to collect seeds to find it has all blown away!
In October 1999, when Alice Waters, renowned chef of Chez Panisse in Berkeley, California, first tasted one variety of papaloquelite, she was ecstatic and demanded to know why she had never experienced it before. She purchased every seed packet available from the Underwood Gardens booth at the Taste of the Midwest Festival, an annual event sponsored by the American Institute of Wine and Food.
When we met Alice at Slow Food Terra Madre in Turin, Italy, in 2012, we mentioned this past connection. She immediately remembered the event, and her eyes lit up when we discussed the aromatic flavors and how she introduced them to her restaurant patrons.
It’s always used raw and added at the last minute, giving its signature, unique piquant flavor to dishes. It’s used in fish dishes, salsas and guacamole. There is a memorable guacamole that uses cucumbers and papalo for added depth of flavor that we can’t get enough of. We also really like it in scrambled eggs, fresh salsas, and finely diced in a strongly flavored salad of spinach, arugula, mustard greens, and kale. Devilled eggs take on an entirely new dimension with a couple of leaves finely diced and mixed into the filling. People always try to guess the mystery seasoning and always mistake it for something else.
In restaurants in the state of Puebla in Mexico, it’s common to find a sprig of papalo in a glass jar of water on the table, next to the salt, pepper and salsas — ready to be added raw to soups, tacos, tortas or beans. The diners will take off a leaf or two and tear it up finely before sprinkling it over their meal.
Papalo is very easy to grow and has a history stretching back thousands of years, so give it a try in your herb garden this season!
Achocha – the Unknown Cucumber Relative
Achocha or Caihua (pronounced kai-wa) is an unusual and relatively unknown member of the cucurbit or cucumber family with a difference. Although they share family roots with cucumbers, squash, pumpkin, zucchini and melons, they arealmost completely immune to many of the diseases and pests that attack the other cucurbits – squash bugs, vine borers, cucumber worms and powdery mildew along with other fungal issues.
Achochaare hugely prolific both in leafy shade growth and fruit, making them a dual purpose plant for gardeners looking for a green shade or windbreak which gives a good supply of tasty food.
Originally domesticated in the Andes Mountains, the seeds travelled by trade from modern day Columbia in the north to Bolivia in the south. This ancient crop has been featured on pre-historic pottery and art and is discussedin the book “Lost Crops of the Incas” by the National Research Council. Today, they are widely grown all across Central and South America, as well as in many other parts of the world. For example, achocha is very popular in northern India, Nepal and Bhutan.
The seeds are very intriguing, looking much like flecks of bark or burnt chunks of a rough plant material. The color ranges from a medium brown to an almost black. Each mature fruit will have several seeds in it.
A close-up of the seeds shows how very different they appear from almost all other vegetables, and certainly other cucurbit family seeds.
Another look at the achocha seed. The majority of them have the little tail or protrusion seen here.
Achocha puts on vigorous vine growth with lots of leaves which provide a good shade for other crops. In areas with a long hot season, establishing them early will give better growth as they slow down during the hottest times. Giving them a bit of afternoon shade and protection helps them along, as they are seen growing up through a patch of Butter Daisies and climbing up a trellis.
This is a western facing wall, and they had a bit of a challenge in becoming well established with the afternoon heat. They had morning shade, but were exposed to full sun and heat during the hottest part of the day until almost sundown.
On the opposite side of the wide walkway, they are seen much more established and prolific. This is the east facing wall that is shaded from early afternoon, giving the plants enough protection from high heat and constant sun exposure to really take off.
This was the most productive planting, giving handfuls of fruit each harvest.
Cindy is holding a young fruit with the blossom cap still attached. At this stage the bark-like seeds are still fairly soft and immature. The fruit will not have completely hollowed out yet, but it is very edible and mild in flavor with a soft texture.
Once the plants begin setting fruit, they should be harvested regularly to encourage continued production. As they begin to produce, you will have handfuls of the fruit to work with!
The tiny, off-white flowers can be seen in the background. It is best to plant at least two plants so they can pollinate each other. The flowers will attract a number of smaller insects to help with pollination, among them the beneficial serphid fly which feasts on aphids, thrips and other soft bodied destructive insect pests.
Another view of the size, shape and color of the achocha fruits, along with the foliage. There are a few different varieties of achocha – some with soft spines and a fatter fruit. Ours are more slender and smooth skinned with no soft spines.
The foliage will sometime raise eyebrows and cause questions, as its long toothy leaves somewhat resemble another controversial plant. There is no relation, but it is a conversation starter!
One handful of fruit leads to discovering another, then another as well…
You’ll see why they have earned the name of “stuffing cucumber” when you slice them open and scoop out the seeds. There are enough recipes using them to fill a thick cookbook, but an easy and delicious starting point is to simply stuff them with sautéed sweet peppers and onions after slicing them open and just warming them up on the griddle.
Very colorful, unique and eye-catching along with being delicious, they will be the center point of the table.
In Central and South America the fruits are eaten either raw or cooked after removal of the seeds. They are also prepared as stuffed peppers; stuffed with meat, fish or cheese and then baked or fresh.
Kids often love to pick and eat them in the garden, and they make an excellent addition to salads. The tender shoots, tendrils and young vines are edible and eaten raw or very lightly cooked.
Building a Recycled Growing Bed
A growing bed can be made from many materials, but when you factor in the ability to make a growing bed from recycled components, then the opportunities become almost limitless. It makes sense in so many ways to make your raised beds from an already-used materials. You will often save a significant amount of money while contributing less to the growing landfills. In addition, you reduce the amount of raw resources used to make new building materials. Often you will find your options are much broader when looking at recycled stock, as the solution can more easily present itself when your mind is more open and relaxed, without a fixed design idea.
This is exactly what led to our finding and choosing this particular metal from our local salvage yard. We know we needed a structurally sound, ecologically friendly and long lasting substance for our raised beds in our garden. The pricing on new lumber which could be in contact with soil for long periods of time was not realistic for the amount of beds we needed to make. One by one, every other reasonably available construction material and method fell out as being much too costly, much too labor intensive or not suitable for our climate.
All of this led us to our local salvage yard. When we let the person know what we were looking to do, he immediately pointed us in the direction of some large-scale roofing they had recently recovered. After looking at a couple of different options, we came across these 3 foot wide and 20 foot long sections of really heavy galvanized steel with most of their avocado green paint still attached. They were heavy enough that it was hard to turn one section over to look at the other side.
When we turned a smaller section over and saw how well it dove-tailed into the long section, we knew we had a custom-made solution to our raised beds. All at a price that was pennies on the dollar of other solutions we had looked at, with a much longer lifespan as a bonus.
We have now used these as raised beds in our garden for almost a decade, with no problems. We recently moved the two smaller beds in our greenhouse and discovered photos of when we made the beds initially and wanted to share the process with you.
Please use this as a guiding hand, suggesting what can be done; don’t go out and expect to find this exact material waiting for you. If you go with an open mind, you just might be surprised at just how well what you find works in your particular garden!
The project started out with our finding some really heavy duty galvanized steel corrugated roofing at our local salvage yard. We then rented an electric nibbler tool to split them lengthwise, as they were too wide or deep to use by themselves.
This is the pile after getting it home, splitting it on the flatbed trailer and then unloading them. A full day’s work!
The unusually large corrugations worked perfectly for us, as we flipped the ends over so they would mate with the sides, creating interlocking tabs. The material is heavy enough for us to just screw together, without needing extra supporting material.
The outside view shows the middle tab already cut, bent over and screwed together. These are strong enough to stand on the top of the sides, once the box is constructed!
Using a Sawzall – an electric reciprocating saw – the tabs are cut. There are top and bottom screws in addition to the middle ones.
After cutting, they are bent over into the channel to be screwed together, making a very strong joint or connection.
A close-up look at the finished middle tab. We used self-tapping screws to eliminate the need to drill a starter hole.
Another feature of the unique corrugations is the channel in the bottom of the side panels which perfectly fits a ¾ inch sheet of marine grade plywood that had been previously waterproofed and drainage holes drilled. After installing the plywood and securing it into the channels, we added a heat cable and hardware cloth on top to protect it from damage from gardening tools. The heating cable is desigened and made specifically for this use and is waterproof with an internal thermostat which shuts off at 70°F.
You can see the channels in the steel in the second and third photos from the top.
For the first few years, we used the bottom heated growing bed in our greenhouse. We made two of them and grew cool season salad greens during the fall, through the winter and into the following spring in the unheated greenhouse.
We used overstock cinder blocks from the local block maker to support the beds.
After installing the beds on the cinder blocks, we put in a bottom layer of sand about two inches deep. The sand keeps the heating cable out of contact with decomposing soil and provides a better heat transfer to the soil on top when the moisture seeps down.
Both growing beds were very successful in growing lots of greens throughout the winter. We often found we couldn’t keep up with all of the greens from just one bed!
The greenhouse is being updated and changed a bit to a grow room, with a solid roof as it gets way too hot in the spring and summer to grow anything, so the growing beds needed to be moved to be more useful and functional.
We experimented with a very simple container garden just off of our back deck last year – with great success. It was very close and convenient for fresh herbs and often used fresh greens – just a step out the back door! The containers were all recycled plastic – from old horse water tubs to industrial food shipping barrels cut in half. They were simply put on top of a base of cinder blocks three high for less bending and ease of gardening. Everything was arranged in a “U” shape, with access to standing on all sides.
They worked very well, so we expanded the container gardening space with adding the two growing beds on each long side of the “U”.
The slightly shorter growing bed is next to an old 100 gallon horse water tub, containing garlic chives and I’itoi onions, both acting as perennials in our climate. This photo is from the very beginning of March, after a cold and wet winter that turned warm in early spring.
Here’s a look at the updated container garden, just after moving the second growing bed. The two large plastic containers in the foreground were what we used last season and were moved to make room for the larger growing bed.
