Passiflora vitifolia is a spectacular red-flowered passion vine native to a broad region stretching from Costa Rica to northwestern South America. The deeply lobed green leaves resemble those of grapes—the grape genus is Vitis. The leaves are an important food source for larvae of Heliconius butterfly species; the adults visit the flowers to obtain nectar.

Pollinated flowers are followed by 5-inch, speckled, egg-shaped fruit with edible, juicy, whitish pulp. The fruit is very sour until fully ripened.

This is a large, and fast-growing vine (to 20 feet) that requires a warm, humid greenhouse with bright light to thrive in the Chicago area.
