What is a Ground Cherry?
The paper husks of ground cherries may make you think of Chinese lanterns, but don’t confuse them with Physalis alkekengi, the plant actually called Chinese lantern! The ground cherry, Physalis pruinosa, is related to the tomatillo. Its scientific name means “bladder,” which refers to the outer husk. Lanterns are certainly a better visual!

Native Area
Ground cherry is native to parts of the Americas, including Argentina, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Paraguay, and Venezuela. It is a perennial that returns each year in USDA hardiness zones 8 and higher and can be grown as an annual in cooler climates.

Characteristics
Ground cherry is indeterminate and will continue growing until it dies. Unlike tomatoes and tomatillos, ground cherries stay close to the ground, so you’ll need some space to let them sprawl.

Start the seeds indoors in late winter, transplant them outside in the spring, and you’ll get fruit in late summer and into fall.

People grow ground cherry for the ripe fruit that falls to the ground. Every variety tastes a little different, but you can expect some sweetness from each one. Some varieties will seem savory, and others may taste like fruit with a hint of vanilla! You can use ground cherry fruits in pies, salsa, jams, and other dishes you might use tomatoes or fruit in.

Varieties
The Virginia ground cherry is native to the northeastern United States and is one of the few varieties that is a perennial down to zone 6. It’s slightly sweet, making it a decent option for jams and pies.

‘Aunt Molly’s’ is another sweet variety that tastes a bit like pineapple. The husks are much rounder than other varieties.

Physalis peruviana is known by several nicknames, like goldenberry, poha berry, Inca berry, and Peruvian ground cherry. It’s not as sweet as the ‘Aunt Molly’s’ variety, and it has a taller growth habit, reaching up to four feet. The husk comes to a point at the end.

Often called ‘Goldie’, Physalis pubescens has smaller fruit than other varieties, but it’s quite sweet and pairs well with chocolate.

Physalis grisea is often nicknamed the strawberry tomato or the grey ground cherry. It’s not as common as other varieties, but it’s fun to grow because the tiny little hairs make it look grey.

Planting
Start ground cherry seeds indoors six to eight weeks before the last frost. They need a long growing season, so it’s good to get a head start. Set the seeds an eighth of an inch deep and lightly cover them. The soil should be 70-90°F (21-32°C) and should stay moist to help the seeds germinate.

The germination process should take one to three weeks. You can keep your seedlings in a sunny window or use a grow light to make sure they get at least eight hours of light each day.

Transplant seedlings outside after all danger of frost has passed. If you want to move them to a container, choose something with a drainage hole so excess water can drain out. For best results, the container should be at least eight inches deep and twelve inches wide.

If you to grow your ground cherries outside, space them one and a half to two feet apart so they can have plenty of room to grow. Give them a thick layer of mulch to retain soil moisture, but make sure the soil is well-draining.
