Common Names: Passion Fruit, Granadilla, Purple Granadilla, Yellow Passion Fruit Related Species: Fragrant Granadilla (Passiflora alata), Red Granadilla (P. coccinea), Maypop (P. incarnata), Yellow Granadilla (P. Laurifolia), Sweet Granadilla (P. ligularis), Sweet Calabash (P. maliformis), Banana Passion Fruit (P. mollissima), Giant Granadilla (P. quadrangularis). Origin: The purple passion fruit is native from southern Brazil through Paraguay to northern Argentina. It has been stated that the yellow form is of unknown origin, or perhaps native to the region of Brazil, or is a hybrid between P. edulis and P. ligularis. Cytological studies have not borne out the hybrid theory. In Australia the purple passion fruit was flourishing and partially naturalized in coastal areas of Queensland before 1900. In Hawaii, seeds of the purple passion fruit, brought from Australia, were first planted in 1880 and the vine came to be popular in home gardens. Adaptation: The purple passion fruit is subtropical and prefers a frost-free climate. However, there are cultivars that can take temperatures into the upper 20's (°F) without serious damage. The plant is widely grown in California as far north as San Jose, the Monterey Bay Area and the San Franciso Bay Area. The vines may lose some of their leaves in cool winters. The roots often resprout even if the top is killed. The plant does not grow well in intense summer heat. The yellow passion fruit is tropical or near-tropical and is much more intolerant of frost. Both forms need protection from the wind. Generally, annual rainfall should be at least 35 inches. Passion fruit vines make good container specimens but require maintenance. They perform well indoors.
