Passion Fruit is a climbing vine.
More precisely, it is a very vigorous and fast growing climbing vine. Passion fruit vines have large, three lobed leaves, little tendrils that wrap themselves around whatever they can get hold of and tend to have an appealing ambiance to a garden.
The fruit is either yellow or purple (depending on the variety, see below), round, and about five to eight cm across. It has a smooth, thick, pithy rind, filled with sweet, aromatic pulp, juice and seeds. Passion fruit vines climb up any support, readily and rapidly, and they climb as high as they can.
Purple passion fruit,
The purple passion fruit is a native of Brazil. Purple passion fruit is sweeter.
Commercial growers in cooler climates often use hybrid varieties of the purple and golden passion fruit. That way they get a plant that tolerates cooler weather. (The hybrids have all kinds of fancy names, SuperSweet, Lacey, Purple Gold etc.)
Yellow passion fruit,
(passiflora edulis f. flavicarpa) also called tropical passion fruit. Nobody knows where the tropical passion fruit originated. The tropical passion fruit is slightly bigger, and slightly more acidic. The variety Panama confuses people, because it can be purple. However, Panama is a true tropical passion fruit of the type flavicarpa (which is usually golden).Even though it seems to be a mix, it is not a hybrid!
