Growing Guide: Ground Cherries

You’ve probably grown tomatoes and maybe even tomatillos, but their lesser-known relative, the ground cherry, deserves a spot in your Solanaceae (nightshade family) lineup. Ground cherries have a more sweet, fruity flavor, hence the name ground cherry. They’re well suited to sweeter, dessert-type recipes than their relatives and are tasty fresh, too!

Ground Cherry History

Ground cherries are native to South and Central America and may have originated in Brazil before spreading to Peru and Chile. They were one of the many crops cultivated by indigenous peoples in the Americas before European contact, and Europeans brought them to England in 1774.

English colonists brought them to the Cape of Good Hope, earning them one of their other common names, the Cape Gooseberry. As colonists traveled with them, the plants made their way back to North America. 

While ground cherries were popular with small farmers, they were never commercialized, probably due to their ripening and harvest, which we’ll get into in a bit. Today, they remain popular among specific communities like the Pennsylvania Dutch, who grow them for jams and preserves.

Starting Ground Cherry Seeds

Growing ground cherries is a lot like growing tomatoes! Start your seeds indoors about 6 to 8 weeks before your last frost. Plant the seeds about 1/4 inch deep, and for good germination, maintain a soil temperature between 75 and 85 degrees F.

Ground cherries typically take 7 to 10 days to germinate.

Transplanting Ground Cherries

Ground Cherries should be transplanted out after all danger of frost has passed. Harden off your transplants for a couple of weeks before planting.

Transplant them into a bed that has rich, well-drained, light soil. You may need to amend the bed with compost, as ground cherries are heavy feeders. You should also select a bed that receives full sun.

Rotate Your Ground Cherries

Rotating your crops is essential, and ground cherries are no exception. We like to rotate crops by family. Ground cherries are a member of the Solanaceae family, like tomatoes, peppers, tomatillos, eggplants, and potatoes, so we avoid planting them in beds where any of these crops have grown in the last couple of years.

Ground Cherry Spacing

Unlike tomatoes and tomatillos, ground cherries don’t require trellising or cages. However, they still need proper spacing. Ground cherries have a sprawling, spreading growth form, so you should place them 2 to 4 feet apart. In some varieties, like Mary’s Niagara Ground Cherry, plants can surpass 6 feet wide in good growing conditions. 

Ground Cherry Care

Keep your ground cherries weeded and water consistently. Keep the soil moist but not soggy. After the soil temperature has risen in June, mulching around plants is a good idea. It will help with weeding and prevent the fruits from getting dirty or rotting as quickly around harvest time.

Harvesting Ground Cherries 

Ground cherries are edible and tasty when fully ripe and yellow, and their husk is brown and dry. Usually, this also means the cherries have fallen off the plant and are lying on the ground. Collect your fallen cherries and remove the husks before eating. 

This habit of dropping ripe fruit is one of the reasons ground cherries have never seen widespread commercial interest.

Using Ground Cherries

Ground cherries can be eaten fresh, cooked, or preserved for later. Ground cherries also have a good shelf life and can be kept fresh for weeks before processing. Here are a few of our favorite recipes we’ve found for ground cherries:

Saving Ground Cherry Seed

You may not have to save seeds, as ground cherries have a strong tendency to self-sow. However, if you’d like to steward a variety, we recommend separating varieties by 300 feet for pure seed. You only need one plant to save viable seeds, but if you want to maintain a variety over many generations, save seeds from between 5 and 20 plants.

Processing and saving the seeds is exactly like processing tomato seeds. Squeeze the seeds and pulp into a jar, add about as much water, and let the mixture ferment for 2 to 3 days, stirring once a day. A little mold growth on top is fine.

After fermenting, add more water so that the pulp and non-viable seeds float to the surface and pour them off. You may need to repeat this a couple of times. Then, rinse your good seeds in a mesh strainer or cheesecloth with clean water.

Let your seeds dry out of direct sunlight for three weeks. Then, store them in an airtight container out of the sun.

New Varieties for 2024!

New year, new seeds! We’re heading into 2024 by offering a few new varieties on our catalog and website. Some of these are heirlooms that have been shared with us, like the Turkish Cekirdegi Oyali Watermelon. Others are new varieties like Xiye Butternut Squash that have recently been bred for features like disease resistance, climate adaptability, and flavor. Not all of our new varieties are available on the website yet, but these fourteen are, so be sure to grab them while our seed supplies last!

Adirondack Blue Seed Potato

This new variety from Cornell University will quickly become one of your garden staples. Adirondack Blue produces moist, stunning, blue-skinned, and blue-fleshed potatoes. The vigorous plants support good yields.

Ashwagandha PlantAshwagandha (Withania somnifera) 

Ashwagandha is an important herb in Indian traditional medicine. Herbalists use the roots to strengthen the immune system, increase resiliency to stress, and relieve insomnia. You can also use the berries as vegetable rennet. 

Ashwagandha is native to the dry regions of India, the Middle East, and North Africa, where it grows to be a small shrub. It’s in the solanacea or nightshade family, like tomatoes and peppers. In the U.S., it’s only perennial to USDA zone 10 but can be grown as an annual in temperate regions. 

Appalachian White Wheat

Homescale grain production is easier than you think, especially with this excellent variety from North Carolina State University. Appalachian White Wheat has high protein (14%) and mild flavor.

It’s a semidwarf variety with good disease resistance to most wheat diseases of the Mid-Atlantic. ½ pound sows 125-250 square feet as a cover crop or 250 square feet as a grain crop.

Biquinho Spice Pepper PlantBiquinho Spice Pepper (C. chinense)

These little Brazilian Peppers are relatively mild and delicious pickled. In Brazil, they’re a popular snack in botecos or neighborhood bars and are often served with sausage or fish. They get their name, which means “little beak” in Portuguese, from their inverted tear-drop shape.

Biquinho Spice Peppers grow about 2 feet tall and are highly branched. The peppers are small, about ½ by ¾ inches, and relatively mild. Their harvests are more likely to taper off than with other Chinese types. 

Cekirdegi Oyali WatermelonCekirdegi Oyali Watermelon

Cekirdegi Oyali is a Turkish heirloom introduced to the U.S. by our friends at Two Seeds in Pod. This variety produces small melons, about 5 pounds each, with sweet orange flesh.

One of the joys of saving seeds from this variety is its unique-looking seeds, which look like they have been carved. As they dry, the black seed casing cracks, revealing the white seed inside.

Fiesta Trailing Mixed Color Nasturtium (Tropaeolum majus) 

With a stunning mix of yellow, orange, rose, and crimson blooms, Fiesta is a must-have for any nasturtium lover. These plants produce long trailing vines of attractive, edible leaves and flowers with watercress-like flavor that works well for salads and garnishes. 

Green Finger CucumberGreen Finger Cucumber

Green Finger is an excellent variety for market and home growers bred by Cornell University. It produces crisp, thin-skinned cucumbers 8 to 10 inches long. They have great flavor and productivity and consistent fruits.

Green Finger shows excellent disease resistance to powdery mildew, papaya ring spot virus, watermelon mosaic virus, zucchini yellow mosaic virus, and high tolerance to angular leaf spot. It matures in sixty days.

Enjoy them right off the vine as you stroll through your garden, in a salad, pickled, or as an addition of crisp freshness to your cool summer drink!

Pink Zinnias

Who doesn’t love zinnias? These easy-to-grow flowers are staples for all kinds of flower gardens, so we jumped at the chance to add a new zinnia to the listings. 

Pink Zinnias produce a smorgasbord of pink flowers on tall plants, including a lovely mix of single, double, and semi-double flowers.

Spinners Ivory Cotton, Seeds, Yarn, and needleSpinners Ivory Cotton

This new cotton variety was bred by Cindy Conner through Homeplace Earth’s Cotton Project right here in Virginia. She bred Spinners Ivory from a cross of green and brown varieties.

Cindy named this variety for its naked seeds (no lint), making it easy to remove by hand or spin right off the seed. It has a short staple and off-white color.

If you’re interested in cotton or fiber arts, we highly recommend you read Cindy’s book Homegrown Flax and Cotton: DIY Guide to Growing, Processing, Spinning & Weaving Fiber to Cloth.

Ten Xiye Butternut SquashesXiye Butternut Squash (C. moschata)

This new winter squash was bred by Care of the Earth Community Farm in Corryton, Tennessee, and named in honor of climate activist Xiye Bastida. This variety was bred from a cross between San Jose Mountain Club Squash (from Costa Rica) and Waltham Butternut.

This great-tasting squash was bred to resist downy mildew and tolerate variable and unpredictable climatic conditions. The plants are fully vining and very productive. Xiye Butternut is sweet and nutty and has a caramel or butterscotch flavor when roasted, and the exterior color is a deep tan. 

Selection is ongoing for butternut shape, size (selecting for 4 lb. size), smaller seed cavity, dry matter content, flavor, and ability to store for at least three months. Xiye is currently in its 7th generation; expect a bit of variability for all characteristics.

 

Adding new varieties to Southern Exposure Seed Exchange and preserving old favorites is always a careful balancing act. Whether heirlooms or newly bred varieties, these fourteen crops have earned a place on our website and catalog for their delicious flavor, hardiness, disease resistance, beauty, and productivity. Consider adding one of these new varieties to your garden this season, and be sure to let us know how it goes!

Tips for a Drought & Heat-Tolerant Garden

Many of you probably saw that the USDA released a new hardiness zone map just a couple of weeks ago. Some of you may have gotten a further surprise, glancing at the map to see that your hardiness zone had changed! This little jolt may have helped confirm signs of climate change you’ve already noticed in your garden, like milder winters, hotter summers, erratic weather patterns, or earlier budbreak. While we can’t totally predict the effects of a changing climate, we do expect to see generally hotter, drier summers, and many of our customers do too. Here are a few ways to prepare for a heat-tolerant garden this season.

Grow Drought Tolerant Varieties

Many of our old heirlooms come from a time when irrigation on a small family farm was non-existent. When you look at many old Southern heirlooms like ‘Iron and Clay’ Southern Peas, Texas Gourdseed Corn, and Genuine Cornfield Pole Beans, you’ll find varieties that have tolerated heat and drought for years without much assistance.

Grow Short-Season Crops

One way to beat the heat is to avoid it. Crops that are fast-maturing stand a better chance of producing before they even have to face extreme temperatures or drought. Short-season bush beans are a great crop for this strategy. Varieties like ‘Provider’ can mature in as little as 48 days. In hot areas, crops like these should make up a good portion of your spring garden and will allow you to get another round in autumn. 

You can also opt for smaller versions of some of your typical slow-maturing favorites. ‘Golden Midget’ has become one of our favorite small watermelons for its ability to produce in just 72 days. ‘Table Queen’ winter squash, which produces in just 80 days, is another great option, especially when compared to varieties like ‘Big Max,’ which takes 115 days to mature.

Plant Perennials

Many perennials are quite drought-hardy once established. Their long lives allow them to develop deep tap roots and extensive root systems. This includes many fruit and nut trees and perennial herbs and vegetables like figs, almonds, horseradish, and asparagus. They may require watering initially, but once established, they should do pretty well on their own, especially if you keep them mulched.

Many of our native wildflowers, like Rudbeckia, echinacea, and Early Horse Gentian, have more extensive, deep root systems than many ornamental flowers. Opting for more species like these can reduce watering and maintenance in flower beds.

Use Companion Planting and Intercropping

The classic example of companion planting is the Three Sisters Garden, where corn, beans, and squash are interplanted. In this example, the squash vines help shade the soil for the corn and beans, keeping it cool and moist. 

While this example has become famous, Native Americans often interplanted other crops like sunflowers and amaranth, too, and you can use the same principles with other crops. Cucumbers can be grown beneath sorghum, roselle, or other tall crops to shade the soil. Bean tunnels or trellises can create shade to stretch the season for cool-weather crops like lettuce and broccoli. 

Diversifying in this way has other benefits, too. If one crop fails, you’ll still have used your space well. Multi-crop beds also tend to be more disease and pest-resistant than monoculture plantings. 

Use Cover Crops and Mulch

Bare soil is dead soil, especially when the temperatures climb. Keep your soil cool, moist, and healthy by keeping it covered. Cover crops are ideal for edges, pathways, and resting beds as they add nitrogen and organic matter to the soil. Some, like buckwheat, are very quick-growing and can be cut, dropped, and used as mulch for transplants. 

Use mulch around plants and in heavy-use pathways. Mulch doesn’t have to be beautiful and perfectly matching. Try woodchips, straw, hay, grass clippings, or old leaves.

Use Your Shade

Shade isn’t usually a vegetable gardener’s friend. However, in the middle of a hot summer, plenty of cool-season crops will benefit from a bit of shade. Use the spaces around fruit trees or sides of buildings to experiment with getting better summer production from tender crops like green mixes.

Save Seeds

Each year, you have an opportunity to adapt your favorite varieties to your climate. Take it. 

You may not have the time or energy to save all the seeds for your garden, but you can probably pick a few favorites. Maybe there’s a tomato you couldn’t live without or a pole bean your family has enjoyed for years. If you save seeds from the plants that performed best each year, you will shape that crop’s future to be specifically adapted to your growing conditions. 

Gardening has never been easy, and it isn’t getting any easier! Climate change brings warmer temperatures, drought, new pests, and more. Hopefully, these tips will help you adapt your garden strategy to climate change and have a productive year.
