Cape gooseberry is a South American Solanaceae that produces small, sweet-tart orange fruit enclosed in a papery husk. It is a perennial in frost-free areas, treated as an annual elsewhere. Extremely easy to grow in warm climates and self-seeds aggressively - to the point of becoming a weed in some subtropical and tropical gardens.

How to Grow Cape Gooseberry in Tropical Australia
When to Plant
Can be planted year-round. Perennial here - plants survive for multiple years. WARNING: cape gooseberry self-seeds prolifically in tropical gardens and can become invasive. Control unwanted seedlings.
- Soil
- Well-drained, moderately fertile soil. Tolerates poor soil better than most Solanaceae. Overly rich soil produces leafy growth at expense of fruit.
- pH Range
- 5.5-7.0
- Sunlight
- Full sun to partial shade (minimum 4-6 hours). Produces best in full sun but tolerates more shade than capsicum or tomato.
- Spacing
- 90cm apart, 120cm between rows
- Watering
- Moderate water needs once established. Surprisingly drought tolerant for a Solanaceae. Water regularly during fruit set. Excessive watering reduces fruit sweetness.
Companion plants: Basil, Marigold, Nasturtium
Avoid planting near: Other Solanaceae in crop rotation, Fennel
