|Common name||Passion Flowers|
|Germination||Soak seed in warm water for 24 hours before sowing, in a good seed compost at 1/4" deep. For Passiflora seeds, instead of using water you can use a high pulp fruit juice such as passion fruit juice or orange juice. The acid in these juices will soften the shell and speed up germination. Keep damp soil, not soaking wet. Keep pot in warm situation 20°C/68°F, 24°C/75°F. Cover the top of the pot with clear plastic so the humidity will remain high.
When you see some tiny plants starting to sprout, slowly open the top of the pot, a little each day, so that the new seedlings don't go into shock from the humidity being lowered too quickly. Germination of Passiflora can occur in weeks or take several months. If you want to speed up germination, you can use the bottom heat technique, but it isn't a must.
|Scarification / Stratification||If your home is on the low side of 70ºF, your seeds will benefit from bottom heat. Give warmth from underneath to stimulate early growth, and to help seeds to germinate. The ideal situation is to maintain the soil temperature at 70ºF. For this, you use an electric soil warming cable kit, or a heating mat that goes under your flats; or any other source of heat. With the proper temperature, you will cut by 2 or 3 the germination time.
