Ground cherries are a delightful addition to any garden, offering sweet, tropical-flavored berries encased in papery husks. These versatile plants are easy to grow, prolific, and perfect for snacking, making them a favorite in children’s gardens and beyond.
What Are Ground Cherries?
Ground cherries, also known as husk tomatoes or strawberry ground cherries, are part of the Physalis genus. The most common species for gardening, Physalis pruinosa, is native to Mexico but has gained worldwide popularity. Varieties like Aunt Molly’s, Cossack Pineapple, and Goldie are particularly well-suited to home gardens.
The cousin species Physalis peruviana, often called Cape gooseberry or Inca berry, is also grown for its similar fruit. Both thrive in climates warm enough to grow cherry tomatoes and are excellent sources of vitamins A, C, and antioxidants.
How to Grow Ground Cherries
Starting Seeds
Ground cherry seedlings are rare to find, so it’s best to start from seed. Since the seeds have hard coats, germination can be slow. Begin sowing 6-8 weeks before the last spring frost, around two weeks earlier than tomatoes.
- Tips for Germination: Maintain temperatures above 70°F (21°C) with a heat mat for optimal results.
- Care: Grow seedlings under bright indoor lights and harden them off gradually before transplanting outdoors.
Planting in the Garden
Ground cherries prefer fertile, well-drained soil with moderate nitrogen levels. Add compost and organic plant food to each planting hole. Wait until the soil is warm, and protect young plants from cold winds with cloches or tunnels if needed.
Unlike their upright relatives, ground cherries spread horizontally, with some upright growth appearing later. To keep fruits clean and reduce splitting, mulch with cardboard or other materials to maintain consistent soil moisture.
Pest Alert: Watch for tomato hornworms, which can damage plants. Use a black light flashlight at night to easily spot and remove them.
Growing in Containers
Ground cherries grow well in containers, with one plant thriving in a 10-gallon (40-liter) pot. Raised containers make harvesting easier by keeping branches elevated, which is especially beneficial in children’s gardens.
Harvesting Ground Cherries
Ground cherries are ripe when they fall from the stem. Their husks protect them for several days, allowing you to gather fruit every 2-3 days. To harvest:
- Gently lift branches and scoop up fallen fruits.
- In raised containers, sweep fallen cherries into a dustpan for easy collection.
Store ground cherries at room temperature in their husks for up to a week. Remove the husks and rinse before preserving or cooking.
Using Ground Cherries in the Kitchen
Ground cherries are incredibly versatile. Enjoy them fresh as snacks or incorporate them into recipes:
- Sweet Dishes: Bake into pies, cobblers, or coffee cakes.
- Savory Pairings: Add to salads, salsas, or pair with nutty cheeses.
- Creative Uses: Top yogurt or cereal, or roast into a sweet-savory spread.
For preserving, make jams, chutneys, or salsas. Alternatively, freeze ground cherries on a cookie sheet, then store them in an airtight container for later use.
With their unique flavor and ease of growth, ground cherries are a rewarding crop for gardeners of all levels. Whether fresh, cooked, or preserved, they add a tropical twist to any dish!
