Passiflora edulis f. flavicarpa, commonly known as yellow passion fruit or lilikoi, is a vigorous tropical vine native to South America that produces larger golden fruits compared to the purple variety. Seeds require warm conditions and pre-treatment to overcome dormancy, with germination typically occurring within 2-8 weeks under optimal conditions. This forma represents 95% of commercial passion fruit production worldwide.
Before sowing
Pre-treatment is essential. Soak seeds 24-48 hours in warm water. Light mechanical scarification optional. Gibberellic acid treatment can improve germination rates
Sowing
What to expect
Tips
Use fresh seeds for best results; seed freshness is more important than any treatment method. Maintain warm soil temperature (70-85°F) using bottom heat if necessary. Keep soil consistently moist but not waterlogged. Provide bright indirect light; direct sunlight can stress seedlings. Cover pots with clear plastic to maintain humidity until germination. Be patient—do not disturb soil to check for sprouts. Remove cover once seedlings emerge and provide more light. Fertilize seedlings with diluted balanced fertilizer once they develop true leaves. Transplant when seedlings reach 10-16 inches (25-40 cm) tall.
