About plant names...

The crimson passion flower is native to Costa Rica, Nicaragua, Panama, Venezuela, Colombia, Ecuador, and Peru, in South and Central America. It is becoming naturalized in Hawaii, but is not found in the wild elsewhere in North America.

Identification: These evergreen vines reach 25' (7.6 m) in length. The vine extends tendrils that encircle supports, then coils them like springs to achieve a more robust grasp. This species’ leaves resemble grape leaves, hence the name vitifolia. Dark green leaves have three lobes, and fuzzy undersides. Beautiful red flowers are 5-6" (12-15 cm) in diameter, with 10 petals. (Okay, technically, there are five petals and five petal-like sepals.) Fruits are egg-shaped, green with yellow or white spots, soft and juicy.
