Passiflora macrophylla, known as Tree Passion Fruit, is a rare tropical species native to the humid lowland rainforests of western Ecuador and Colombia. This species has pronounced seed dormancy and requires warm, moist conditions to germinate successfully. Seeds typically germinate between 2-8 weeks when provided with proper warm temperature, moisture, and darkness.
Before sowing
Seeds have hard seed coat and require pretreatment. Combine scarification with warm water soaking for best results
Sowing
What to expect
Tips
Keep soil continuously moistened but not waterlogged and cover with plastic or glass to maintain heat and humidity. Place container in a warm location with temperatures between 25-30°C (77-86°F). Light inhibits germination, so provide darkness during germination. Provide bottom heat to accelerate germination. Keep seedlings warm; tropical origin requires minimum 15°C. Avoid crowding seedlings as they are sensitive to proximity. Transplant to individual containers when large enough to handle. Do not let soil dry out during germination as this stops the process.
