Passiflora capsularis, known as the capsule-fruited passionflower, is a tropical climbing vine native to Central and South America. The species produces delicate, vanilla-scented white flowers and distinctive ribbed, reddish-purple capsular fruits. Seeds germinate in 4-12 weeks with proper pre-treatment, requiring warm temperatures and consistent moisture.
Before sowing
Soaking seeds in warm water for 24-48 hours is essential. Optional light scarification with sandpaper or alternative soaking in acidic juices (orange, lemon, or passion fruit pulp) to speed germination

What to expect
Tips
Soak seeds for 24-48 hours in warm water before planting to enhance germination. Light mechanical scarification with sandpaper can be beneficial. Keep soil consistently moist but not waterlogged; use a heat mat to maintain temperatures between 70-80°F for optimal results. Provide bright, indirect light during germination. Seedlings are cold-sensitive when young; maintain temperatures above 21°C. Once established, fertilize regularly and prune to promote branching and flowering. The plant tolerates down to 5°C and flowers readily in containers.
