(Passiflora edulis) Frederick is the premier fruit producing passiflora. If you don't live in USDA Zones 10-11, grow it in a sunny window or greenhouse. It thrives and produces, often the first year, in a pot. The flowers are fragrant and large. The fruit has a purple skin and delicious pulp when ripe. The fruit should never be picked, it must fall from the vine naturally. If it is allowed to wrinkle a bit after collecting, it becomes sweet ambrosia. The plant is very productive in warm areas. This outstanding Patrick Pons-Worley hybrid is vigorous and blooms from late spring until fall. In USDA Zones 10-11, this plant is excellent for a sunny location and makes a good, rapidly growing screen for a fence or outbuilding.
