How to grow Cape Gooseberry
Updated October 2026
Cape gooseberries and ground cherries are husk fruits in the tomato family, close cousins of the tomatillo. Each small golden berry ripens inside a papery lantern and tastes sweet and tangy, somewhere between a tomato, a pineapple and a strawberry. Cape gooseberry (Physalis peruviana, poha in Hawaii) is a tall, slow perennial for warm climates, while the low ground cherry (Physalis pruinosa) crops quickly as an annual across the North.
📖 Our full guide: How to Grow Cape Gooseberry
Not to be confused with: Despite the name, cape gooseberries are not related to true gooseberries and currants. Tomatillos are larger husk fruits of the same genus, used green in salsa.
Where to plant
Both are frost tender and need full sun and warm soil. In the North, set transplants out two to three weeks after the last frost, once the soil is warm. Penn State notes cape gooseberry is perennial only in about zone 8 and warmer and its slow fruit may not ripen in a short northern season, so northern gardeners do best with the faster ground cherry. In Alaska, grow them under row cover or in a high tunnel.
In Florida, the Gulf South, Texas, the desert and California, plant in spring and again in late summer for a fall crop. South Florida can grow them from late summer through winter. In Hawaii, poha has naturalized on open mountain slopes between about 1,500 and 4,000 feet, and University of Hawaii notes plants grow below that but give smaller fruit at lower elevations.
Choosing a variety
Aunt Molly's is a sweet, productive ground cherry (Physalis pruinosa) that has been grown by Pennsylvania German gardeners since the 1800s. For cape gooseberry (Physalis peruviana), look for seed sold as goldenberry or poha; plants are larger and slower but bear bigger fruit over a long season where the climate is warm enough.
How to plant
- Start seed indoors several weeks before the last frost, sowing shallowly in a warm spot.
- Harden off seedlings and plant out two to three weeks after the last frost, when the soil is warm.
- Space ground cherries about 2 feet (60 cm) apart. Cape gooseberries need more room; University of Hawaii spaces poha about 4 feet apart.
- Stake or cage cape gooseberry plants; staking is optional but makes harvesting easier.
- Mulch to keep the soil moist and to catch dropped fruit cleanly.
Watering and feeding
Keep the soil steadily moist, especially while fruit is forming, and avoid waterlogging.
Feed moderately. Dig compost in before planting and give a balanced fertilizer occasionally; too much nitrogen gives large, leafy plants with fewer fruit.
Pruning and care through the year
- Weed carefully, as both have shallow, fibrous roots.
- In frost free areas, cape gooseberry can be cut back hard once a year after harvest to regrow, though fruit size declines with each cycle.
- Ground cherries self seed freely from dropped fruit. Pull unwanted seedlings next spring, as they come up like weeds.
- Rotate away from where tomatoes, potatoes and eggplant grew, as they share pests and diseases.
Harvesting
Fruit is ripe when the husk turns dry and straw colored to tan and the berry inside is golden. Ground cherries drop to the ground when ripe; gather them every few days. Pick in the afternoon after dew has dried so the husks stay dry. Fruit whose husk drops while still green seldom ripens.
Do not eat unripe green fruit, leaves or stems, which contain toxins like other members of the nightshade family. Ripe fruit can be eaten fresh, made into jam or used as a flavoring for ice cream.
Growing in pots
Ground cherries grow well in a pot at least 12 inches (30 cm) wide and deep in full sun. Cape gooseberries need a bigger pot and a stake. Water often in hot weather.
Companion planting
Grow them with crops that like the same warm, sunny summer bed.
Good companions
- Tomato Shares the same warm season, sun and water needs.
- Basil A summer herb for the bed edge that draws pollinators.
Keep apart
Avoid planting these close to cape gooseberry.
Pests and diseases
University of Hawaii lists broad mites, red spider mites and thrips on poha; whitefly is common on all Physalis in warm areas.
Pests to watch for
- Whitefly Tiny white insects flying up from the undersides of leaves.
- Spider mites Pale, stippled leaves in hot, dry weather.
- Thrips Silvery, scarred leaves and fruit.
Cape Gooseberry is rarely troubled by disease.
Common questions
What is the difference between a cape gooseberry and a ground cherry?
Both are Physalis husk fruits. Cape gooseberry (P. peruviana) is a tall, slow perennial with larger fruit, suited to warm climates. Ground cherry (P. pruinosa) is a low annual that ripens quickly, about 10 to 11 weeks after transplanting, so it suits northern gardens.
How do I know when ground cherries are ripe?
The husk turns dry and tan and the fruit drops to the ground. The berry inside should be golden. Gather fallen fruit every few days.
Are unripe ground cherries poisonous?
Unripe fruit, leaves and stems contain toxins, as in other nightshades. Eat only ripe, golden fruit from dry, papery husks.
Can I grow cape gooseberries in the North?
They are slow, and Penn State notes the fruit may not ripen in a short northern season. Ground cherries are the better choice. Start seed early indoors and plant out after frost.
Will ground cherries come back next year?
Ground cherries are annual, but dropped fruit self seeds heavily, so seedlings often come up the next spring. Cape gooseberry is perennial in frost free areas.
Do cape gooseberries need staking?
Not strictly, but University of Hawaii notes staking makes harvesting easier, and it keeps the tall, sprawling plants off the ground.
