Passiflora edulis 'Purple Giant' is a passionflower that produces very fragrant, unusual flowers. The flowers are white, except the base of the corona which is purple; the filaments are curly, as long as petals; 5 to 7cm (2 to 3in) across. Flowering occurs from April to November but may occasionally continue year-round if conditions are right. Flowers will self-pollinate and are followed by green fruit, 6 cm (2 in) long, turning purple when ripe.
Fruits usually ripen from flowering in 80 days. The edible fruits possess pleasant flavour, kind of sweet and a little tart. Evergreen leaves, deeply three lobed, shiny and deep green above, paler and dull beneath.
When grown outside they must be very well sheltered. Passion fruit will do better in a greenhouse or conservatory and will grow big enough to produce fruit roughly 12 months after growing from seed.
The plants are hardy to 1°C (35°F) in winter so protect from any frosts. Ideal temperatures of 15° to 28°C in summer and 13 to 18°C through the winter. 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.
They can be grown in a container, a suitably sized pot for an adult plant would generally be of 30cm (12in) in diameter. If their pot is too large or they have an unrestricted root run then the whole plant will simply get bigger but it will refuse to flower and produce 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 seeds for the next generation.
Seeds are planted 1/2 in (1.25 cm) deep in beds, and seedlings may be transplanted when 10 in (25 cm) high. If taller-up to 3 ft (.9 in)-the tops should be cut back and the plants heavily watered.
Regular watering will keep a vine flowering and fruiting almost continuously. Least flowers develop during the winter season due to short day length. Water requirement is high when fruits are approaching maturity. If soil is dry, fruits may shrivel and fall prematurely
Passion Fruit vines are grown on many soil types but light to heavy sandy loams, of medium texture are most suitable, and pH should be from 6.5 to 7.5. If the soil is too acid, lime must be applied.
