Passiflora mollissima, commonly known as banana passion fruit or curuba, is a vigorous evergreen vine native to the Andean highlands of Venezuela, Colombia, Peru, and Bolivia. The species produces beautiful pink flowers and distinctive yellow, banana-shaped edible fruits with tangy, aromatic pulp. Seed germination is challenging due to physical dormancy in the seed coat; however, proper pre-treatment with soaking and mechanical scarification can significantly improve germination rates from 9 to 84 days.
Before sowing
Combination of soaking and mechanical scarification is most effective. Physical dormancy present in seeds requires treatment to break.

Tips
Germination starts after 9 days with 50% of final germination reached within a month. Use bottom heat at 70-80°F (21-26°C) to accelerate germination to 1-2 weeks; lower temperatures significantly delay or inhibit germination. Maintain high humidity with clear cover; gradually open cover as seedlings emerge to prevent shock. Seeds exhibit physical dormancy; stored seeds require pre-treatment, but fresh seeds from fruit pulp germinate faster. Handle fragile white roots carefully when transplanting. Keep soil consistently moist but not waterlogged. Avoid direct sunlight during germination; use artificial lighting if necessary. Seeds show erratic germination and may take up to 12 months, so patience is essential. Cold stratification may help but is not required.
