Not only do they produce mouth-wateringly delicious fruit, passionfruit vines can also serve as a stunning camouflage over unsightly walls and fences. Position your passionfruit vine in full sun with protection from strong winds. In colder climates, choose a spot in front of north facing wall to utilise to radiated heat.The passion fruit is a vigorous, climbing vine that clings by tendrils to almost any support. It can grow 15 to 20 ft. per year once established and must have strong support. It is generally short-lived (5 to 7 years).Passionfruit vines grow extensive root systems so ensure the spot you choose to plant has plenty of space, free from weeds, competing plants and grass. They will also spread up to 10 meters squared so choose or build a structure that can accomodate it. Passionfruit vines can be trained to grow along your fence, on a trellis or over an arbour, just install some wire or mesh to support its tendrils. The nearly round or ovoid fruit, 1-1/2 to 3 in. wide, has a tough rind that is smooth and waxy and ranging in hue from dark purple with faint, fine white specks, to light yellow or pumpkin-color. Within is a cavity more or less filled with an aromatic mass of double walled, membranous sacs containing orange-colored, pulpy juice and as many as 250 small, hard, dark brown or black, pitted seeds. The unique flavor is appealing, musky, guava-like and sweet/tart to tart.
