Passiflora caerulea (Passifloraceae) is a vigorous semi-evergreen climbing vine native to Brazil and Argentina. It can reach 32 feet, climbing by tendrils. The exotic flowers are about 4 inches across with white petals, a corona of blue-purple filaments, and a prominent central column of reproductive structures. Oval orange fruit follows, containing edible pulp surrounding the seeds.

Blue passion flower thrives in full sun on well-drained soil with moderate moisture. It blooms on current season's growth from summer through fall. In mild climates it is semi-evergreen; in colder areas it may die to the ground and regrow from the roots. It is the hardiest commonly grown passion flower species. The fruit is edible but generally bland compared to commercial passionfruit (P. edulis). Hardy in Zones 7a to 8b.
