What Are Ground Cherries?
What it is
Ground Cherry · Physalis pruinosa / pubescens
A ground cherry is the fruit of Physalis pruinosa or P. pubescens, in the nightshade family — close kin to the tomatillo and the goldenberry (Physalis peruviana). Each waxy berry ripens hidden inside its own papery husk (the calyx), which is where the 'husk cherry' name comes from.
Why you won't find it in grocery stores
Two reasons, both economic: ripe fruits naturally drop to the ground, so harvest means gathering fallen fruit by hand — heavily labor-intensive — and the opaque husk means a farmer can't judge ripeness without opening each one. Nobody grows that at commodity scale, so the supply is small farms and market tables.
What it tastes like
A juicy, waxy berry with tiny edible seeds and a sweet-tart flavor most often described as pineapple + vanilla, with savory tomato-adjacent undertones — unmistakably a nightshade, but a dessert-leaning one.
When it's in season
Late summer through autumn — at most markets that means August and September pints.

How to spot it at a farmers market
Sold by the pint or half-pint, each berry inside a dry, light-beige papery husk. Ripe = a golden-yellow to orange-yellow waxy sheen inside a tan husk; skip green-tinged fruit. Market ID trick: a ground-cherry husk has 5 ribs, a goldenberry husk has 10 — count the ribs and you'll never confuse them.

Frequently asked questions
What do ground cherries taste like?
Sweet-tart — most people land on pineapple with vanilla, with a savory tomato-family undertone. The berry is juicy and waxy with tiny edible seeds.
Are ground cherries safe to eat?
The ripe golden fruit is. Green fruit, leaves, and the papery husk are toxic — they carry nightshade alkaloids (solanine/solanidine), highest in unripe berries. And if you're allergic to tomatoes, skip ground cherries entirely.
How do I tell a ground cherry from a goldenberry?
Count the husk ribs: ground-cherry husks have 5, goldenberry husks have 10. Goldenberries (Physalis peruviana) are the larger South American cousin sold in supermarkets; ground cherries are the smaller market-table native.
When are ground cherries in season?
Late summer through autumn — August and September are the pint-basket months at most farmers markets.
Where to find it
Small growers are the whole supply chain for produce like this. Ask at your local farmers market, check farm stands near you, or search by ZIP with the market finder — and if a vendor doesn't have it, ask who might; growers know each other.
