| Banana passionfruit is a vigorous evergreen vine in warm climates. It produces stunning pink flowers followed by large banana-shaped edible fruit that turn yellow when mature. The plant requires a moist, well-drained soil in a sunny location. It can tolerate down to -6 °C (20F) in winter. Banana passionfruit can be successfully grown as a pot plant. Soak the seeds for 24 hours. Soaking is beneficial in two ways; it can soften a hard seed coat and also leach out any chemical inhibitors in the seed which may prevent germination. 24 hours in water which starts off hand hot is usually sufficient. If soaking for longer the water should be changed daily. Seeds of some species swell up when they are soaked. As each seed swells it should be removed and sown before it has time to dry out. and the remainder pricked gently with a pin and returned to soak. Sow seeds in a peaty compost, “just cover” with 6mm (¼”) of soil as the seeds need light to germinate. Germination of Passiflora can occur in weeks or take several months. If your home is on the low side of 20°C (68°F), your seeds will benefit from bottom heat with an electric soil warming cable kit, or a heating mat. It will stimulate early growth, and help seeds to germinate and cut the germination time by half. Cover the top of the pot with clear plastic so the humidity will remain high. 10 seeds |
