Passion Fruit or Granadilla comes from the plant known as Passion Vine or Passion Flower (Passiflora edulis / P. edulis flavicarpa) and is a native to central South America. Preferring loamy soil and humid, but cool situations, the vine produces a round purple fruit that is full and heavy at maturation. The Passion flower from which the fruit develops has a striking arrangement of stamens and petals of various shades of purple and white.
The round/oval fruit is aromatic, sweet and tangy, having a guava-like flavor. Growing to 1.5 to 3 inches wide, the outer surface of the fruit is smooth, waxy, and tough, becoming wrinkled and deeper in color as it ripens. Inside, the fruit is segmented into membranous sacs of orange-colored juice-filled pulp and many small dark-brown edible seeds. Each fruit may yield as much as 25 ml of juice from 2 fruits. It is used to flavor beverages, ice cream, and various pastries and cakes.
