Physalis physalis Physalis (cape gooseberry/ground cherry) is a warm-season Solanaceae bearing sweet, citrusy berries inside a papery husk. Physalis peruviana tends to be taller (80–150 cm) and benefits from staking; Physalis pruinosa (‘ground cherry’) is more compact (30–60 cm) with earlier ripening, better for short seasons. Plants tolerate some drought but set best with steady moisture and heat. In cool climates, grow in a greenhouse or against a south-facing wall for reliable ripening. The husk turns papery and tan to golden as fruits mature; ripe berries often drop to the ground when ready. Growing conditions LightFull sun; at least 6–8 hours of direct light daily. In cooler regions, a warm, sheltered, south-facing spot or greenhouse is ideal. Soil typeWell-drained, fertile sandy or loamy soil enriched with compost. Avoid heavy, waterlogged clay. Mulch to keep soil warm and evenly moist. Water requirementModerate and consistent. Keep evenly moist but never soggy; allow the topsoil to dry slightly between waterings. Nutrient requirementModerate. Start with compost-rich soil; avoid excessive nitrogen which promotes foliage at the expense of fruit. Use a balanced feed early, then a potassium-rich feed during flowering and fruiting. Back to plant list
