Physalis peruviana, commonly known as golden berry or cape gooseberry, is a tender perennial native to the Andean highlands of South America. This member of the Solanaceae family produces sweet, tangy fruits enclosed in a distinctive papery husk. Seeds are best started indoors in a protected environment 8-12 weeks before the last frost date, as they require consistent warmth and light to germinate successfully.
Before sowing
No pre-treatment needed — sow directly.
Seeds have low dormancy but exhibit physiological dormancy that can be released by water. No pretreatment is necessary; seeds germinate readily under appropriate conditions.
Sowing
What to expect
Tips
Keep soil consistently warm (70-85°F / 21-24°C) and moist but not waterlogged during germination. Provide 8+ hours of light daily (bright light or grow lights significantly speeds germination). Press seeds barely into soil surface without covering deeply—seeds need light to germinate. Maintain well-drained substrate to prevent fungal diseases. Germination can be slow (2-3 weeks); patience is essential. Once seedlings develop 2-4 true leaves, harden off gradually before transplanting outdoors after all frost danger has passed. Avoid temperatures below 60°F or above 95°F, as both inhibit germination.
