Passionflower


Overview

Botanical Name: Passiflora incarnata


Order: Malpighiales


Family: Passifloraceae


Passionflower is native to eastern North America. Another species, passion fruit (Passiflora edulis, is cultivated for its edible purple fruit. The green fruits of passionflower are edible and turn yellowish when overripe. Some consider passionflower and Passiflora edulis the same species; however, one study [Dhawan et al. 2001] considers them two separate species because of difference in the composition of their compounds.
