Annual Groundcherry - A Native Plant Agriculture Crop

My Personal Introduction story to a newly available Native Plant Agricultural fruit strain

I’ve always hated the taste of raw tomatoes to the point I would gag when accidentally consuming them. Knowing our native ground cherriy species of north america are in the same family as tomatoes; I was very hesitant to eat these native Annual Groundcherries (Physalis grisea) even after spending the energy growing them. In late June of 2025, I finally tried one, then one turned into many as they were so much sweeter than raw tomatoes; about 3 to 4 times sweeter. The flavor ratio was 85% subtle pineapple in flavor and 15% sweet tomato flavor with these first fruits eaten at a light yellow color stage. The tomato flavor was mostly concentrated in the skin. The pleasant fruity smell they left on my fingers had me sniffing all evening. Even though they have plenty of seeds in them, the seeds are very small to the point they’re undetectable as you eat the fruits. Nutritionally the seeds just count as part of the fiber content of the fruit.

These first Annual Groundcherry fruits were light yellow and I sensed it was only 85% ripe because at room temerpature the fruits would darken into a true gold color after a few days. So I decided to try a fully ripened Annual Groundcherry fruit, and was smacked in the mouth with an opposite flavor ratio of 75% sweet tomato flavor, and 25% subtle pineapple flavor. So it turns out, when the color of the fruit is light yellow, they are more pineapple flavored than tomato flavored. But when the fruit reaches its deepest ripening stage before decaying, the ratio flips into being a sweet tomato flavor accented by hints of pineapple. Based on your flavor preference, you could pick them at the light yellow stage or finish ripening them indoors in a mason jar at room temperature to get a more sweet tomato dominated flavor. The fruits have a long shelf life, and when picked at a yellow stage they can last in the refrigerator for up to 6 weeks. If the fruits are picked in a fully ripe gold stage, they can last in the refrigerator for 3 to 4 weeks.

Native Range

The recorded occurrences of Annual Groundcherry in the wild are uncommon. This is partly due to most botanists who make these herbarium records - not knowing how to separate this species from the more commonly recorded perennial Groundcherry species such as Clammy Groundcherry or Long-Leaf Groundcherry. Due to the lack of common knowledge about this species, it’s only been officially recorded in very few counties within the southeast, midwest, and northeast. Ecologically its value is the same as the more commonly recorded aforementioned perennial groundcherry species. From Maine to Minnesota, Florida to Eastern Texas and everywhere in between this plant grows well and is fruitful when tended by humans as a fruit crop.

How to grow native Annual Groundcherries - Physalis grisea

  1. In mid spring when frosts are a low possibility; soak your ground cherry seeds in water for 24 hours inside a ziplock or plasticware - inside of your refrigerator to keep the water cold.

  2. Sow the seeds in prepared/cleared beds covered in 1” of saturated compost. The compost will help keep the seeds moist encouraging quick germination. Sow by pressing 5 seeds into the surface of the compost and barely covering them with less than 1/10th inch of compost leaving them just under the surface. Plant groups of 5 to 8 seeds every 2 feet horizontally or vertically depending on the orientation of your bed.

  3. They will germinate within 10 to 25 days depending on spring temperatures.

  4. Typically conditions promote fruit maturity within 60 to 80 days of germination.

Easier than Tomatoes

2 Annual ground cherry seedlings produced 480 grams of ground cherry fruits (1.1 pounds) by August 19th and continued producing fruit until the end of September. These plants were sown directly into the ground in mid April. While they produce a large amount of leaves/vegetation to withstand the large caterpillars of Tomato Hornworms; they did not contract them as host plants this year. Instead other insects chewed small, inconsequential holes into the leaves. To maximize fruit production, I watered them once every 10 days once the summer temperatures soared into the upper 80’s and into the 90’s. Without the supplemental watering they would have still succeeded, though they would have been smaller statured and less fruitful plants as they would appear in the wild.

The mature Annual Groundcherry patch pictured above began growing through the chicken wire, using it as support for its thick branches. This growth pattern suggests they could benefit from tomato cages. If the cages are installed when they are young, they will grow their horizontal branches through the tomato cage after they gain height.

Pictured above is what Annual Groundcherry looks like in late summer if it isn’t watered often. It stays low to the ground instead of growing taller and shrubbier. The fruits are hidden underneath the leaves.

Annual Groundcherry produces small pale yellow blooms that are pollinated by small native bees and sometimes bumblebees.

Pictured above is a moderately ripe Annual Groundcherry next to an unripe groundcherry. Before picking the fruit you can tear open its “Hood” to see the color of the fruit before deciding to pick it. Near-ripe fruits fall to the ground or into your hand as soon as you touch them.

getting access to Native Annual Groundcherry Seeds

We grew Annual Groundcherry this year specifically to produce seed to distribute to the public in some fashion. We saw that the few Annual Groundcherry sources on the internet were unpredictable as far as what species would actually grow from the seed - sometimes even non-native ground cherries are labeled as this native Annual Groundcherry (Physalis grisea). We feel this is a very fun and rewarding native crop for foragers and native plant enthusiasts to produce without much effort so we painstakingly harvested, cleaned and preserved the tiny seeds from our Annual Groundcherry production patch this September (of 2025).

Whether or not I can distribute these seeds is a matter of personal health status. We’ve been able to do 9 Native Seed mix sales in 2025 up to the date of 11/1/2025. If I’m able to do more native plant sales of any kind, that’s where you could find the Annual Groundcherry seed packets for sale.

Black Raspberry - Rubus occidentalis Profile

Black Raspberry

Black Raspberries, like Fox Grapes and Muscadine Grapes, are one of the few native fruit crops that have been used in modern agricultural systems. There are even a few cultivars that are pure Black Raspberry, non-hybridized, such as ‘Jewel’, ‘MacBlack’, and ‘Munger’. Black Raspberries don’t require a full day’s sun exposure to yield well, adaptable to as low as 6 hours of direct sunlight for respectable yields. If you’re planning on growing them for wildlife food, they will attract mostly native birds in the early summer during their fruiting period.

Savanna Planting Pattern for Native Plant Agriculture

The best biologically productivity with a Black Raspberry acreage is to infuse competition friendly savanna trees at 10 to 15 trees per acre. These could be Shagbark Hickory, Red Hickory, Persimmon, Black Cherry, Black Walnut, or Honeylocust. Persimmon, Black Cherry, and Honeylocust carrying higher stocking rates per acre (15), and Black Walnut and Hickory carrying lower stocking rates per acre (10) for proper sun exposure. The combination of the spaced out native trees and thick undergrowth of Black Raspberry would result in a high diversity of native insects and their predators co-existing in the planting.

Planting in the Residential Landscape

Black Raspberries perform best on Eastern, Western, or Northern faced slopes or flatter ground in the home landscape. If you choose to put them up against your house, they will tolerate every orientation except the Northside of your home as there isn’t enough sun for them on the Northside. They tolerate full sun within average moisture soils or higher moisture soils. They are also very tolerant of partial shade. The key to vigorous Black Raspberry growth and fruit production is providing them with 2 inches of water during exceptional summer droughts. Because they fruit in early summer before mid summer droughts take place; watering during the mid summer makes the more vigorous the following year as they’re able to store up more energy through drought-free photosynthesis. The thorns on Black Raspberry aren’t as formidable as wild black berries, so berry picking can be a bit more peaceful with this species. Still the thorns provide enough defense for the Black Raspberry thickets to be chosen by nesting native birds such as the Yellow Warbler Pictured above.

The Rubus genus is widely used as insect host plants and their flowers are an essential nectar/pollen source in the spring landscape of moist prairies, fields, wetland margins, savannas, and open woodlands. They bloom at the same time as many forest spring ephemerals that are in decline from White Tail Deer overpopulation, deforestation, and invasive shrub encroachment. So Black Raspberries help buffer the resources of early foraging pollinators with their highly accessible flowers during the mid spring. Blackberries and Raspberry species are known to support over 150 native moth/butterfly caterpillars. So not only do they provide this essential mid spring pollen/nectar - they also produce caterpillars throughout the summer that are forged for by native birds.

Germination Tips: Black Raspberries require acid scarification to germinate. This mimics the process the seeds would undergo if they were eaten by an animal. After thoroughly crushing the fruit up, exposing the seeds, expose the fruit/seed mash to Sulfuric Acid for 25 minutes. Use retail strength Sulfuric Acid with goggles and chemical gloves and rinse this acid from the seed/fruit mash after the 25 minutes of submersion. Then place the seeds in silty soil within a pot, buried halfway underground. This would happen in Early summer for Black Raspberry as that’s when the fruit ripen. Let the pot sit outdoors all summer, fall, and winter. Then in spring time rinse the silty soil away with a strainer thin enough to catch the seeds, separating them from the silty soil. Sow the seeds in early spring/late winter and expect germination by late spring. This process can also be used for Blackberry species which mature later in the summer.

A Native Vegetable you can Grow this Spring - Evening Primrose (Oenothera biennis)

Wild collected Evening Primrose roots by Jeff Knieser. When it is grown in a garden setting the roots can be twice as large as these pictured.

Evening Primrose is a fairly commonly encountered native wildflower. Indigenous peoples of the midwestern, northeastern, southeastern, and mid-atlantic U.S. cultivated this plant as a food source. Evening primrose roots could be developed into many different seed strains of different root textures, sizes, and flavors with a proper breeding program. As of now collecting seed from most wild populations (or buying seed online) produces palatable roots of good size when grown in an agricultural – low competition setting, and boiled before eaten like potatoes. Its also commercially farmed for its seed production to produce Evening Primrose Oil which is used medicinally. Only the first year root is edible, while the plant is a basal rosette. The second year the plant grows tall and flowers - and by then the root has turned woody and mostly inedible.

Cultivation

Evening Primrose is a biennial adapted to harsh soils as well as higher moisture soils, being most prolific within full-sun. As with most root crops, the more aerated the soil is, the larger the root can grow, though soils that are very sandy may create long skinny taproot formation. Very compacted clay soils will restrict the taproot growth as it does to all plants. Cold-Moist Stratify Evening Primrose seeds for 45 days, before surface seeding them onto cleared/bare soil in the early spring. Harvest the roots in late fall/early winter the same year. Again, you must harvest them at the end of the first growing season, as in the second growing season the root turns more woody and inedible.

In Bloom

Natural History

Evening Primrose would naturally occur where grazing fauna such as Groundhog, Bison, or Elk damage the perennial herbaceous layer of a grassland or meadow community creating a niche for this biennial to germinate and take root among the stunted grasses. In modern time these plants are now often seen on roadsides where herbicide applications, brush mowing, and salt damage create open niches. This is the kind of native plant with the toughness to pop up in a crack within the cement. Wild growing evening primrose roots will naturally be much smaller than those grown in a cultivated garden, due to the difference in vegetation competition.

If you don't want to harvest the roots in year one, you will be rewarded by a profuse set of blooms lasting over 1 months time in midsummer, blooming from the evening into the morning hours and closing during the day. They are very popular with moths at night, and bumble bees in the morning. I chose to write about this plant, because unlike most native foods, evening primrose seeds are readily available for sale online. Be sure to purchase Evening Primrose seed with the scientific name - Oenothera biennis. Look for the companies that sell it by the ounce for the best pricing.
