Passiflora actinia an evergreen vine growing to 10 meters at a fast rate. This species is sometimes cultivated in parts of South America. It may be grown as a houseplant in a sunny South-facing window. Passiflora actinia is an outstanding species that produces masses of sweetly scented flowers in a huge Spring flush starting in April and lasting for months. When September approaches it starts again reblooming for another month or more. Petals and sepals are white or green; the corona is white, banded with mauve and blue. Flowers are about 3.5 inches wide. The flowers open in sunny weather and do not open on dull cloudy days. Fruits of Passiflora actinia are golden-orange when ripe and are edible. The fruits are 4-6", with a delicious, fragrant pulp. The foliage is dark green and oval with a darker underside, up to 4 inches long and 3 inches wide. It is a vigorous grower with slender branches that are easily kept under control. The long tendrils need lots of support for climbing. Grow in sunniest window or greenhouse and provide support of trellis. 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, (4øC/40øF) in Winter. It has proved to be quite hardy and has come back from 20øF temperatures for a short period. It will do best in a loam based mix with a little peat moss. Passion flowers like full sun and will scramble over trees and shrubs to get it. 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. 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 beof 12 inches indiameter.
