Quick description:

Produces edible fruits. Protect from frost.


Passiflora coccinea is native to South America; Bolivia, Brazil (Amazonian), Colombia, French Guiana, Guyana, Peru, Suriname and Venezuela. It can reach 15 to 30 feet high. It climbs by means of clinging tendrils and can be kept as an container plant. The long tendrils need lots of support for climbing. It may be grown as a houseplant in a sunny South-facing window. It is grown for its large, vivid red flowers, rather than for its fruit. Plants can have flowers for much of the year but are seen at their peak in Summer and Autumn. The gorgeous 3-5" flowers feature scarlet or red sepals and petals on which the white and deep purple corona filaments, followed by stripped edible fruits looking like dwarf water-melons. The edible fruit is rounded, relatively large, 5 cm, green, striped and mottled, becoming yellow or orange when ripe. Passiflora coccinea is a strong growing, evergreen climber with dark green leaves. The entire, oblong leaves are 2-5 inches long and 1-2 inches large. Pruning is a must to keep the vine healthy. Prune off less vigorous growth and occasionally prune back vigorous growth to promote flowering. When established, and without care, the passion fruit can easily overtake other garden plants, shading them from sun. Hardiness zone 9-11, (4°C/40°F, -5°C/25°F) in Winter. Protect from frost or plant in frost free areas. Best to keep above 50º F. Keep the atmosphere humid through the Summer and place in full sun, can tolerate partial shade. Exotic, tropical, and loves warm weather. You may need to water your plants on a daily basis during the hottest Summer months. During the Winter the roots should be kept moist, but as growth will be much slower you will probably only need to water once a week, depending on growing temperature. It will do best in a loam based mix with a little peat moss. Fertilize at least once every two weeks in the growing season. If their pot is too large or if they have an unrestricted root run then the whole plant will simply get bigger and bigger but it will refuse to flower and therefore produce the fruits. By limiting the pot size you are limiting the ability to grow and this is seen as a threat, so the natural mechanism is to produce seed for the next generation. A suitably sized pot for an adult plant would generally be of 12 inches in diameter.

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.
