Passiflora

(Passifloraceae - passion flower family)

Passionflower. About 400 species of tendril-climbing vines, native mostly to Central and South America. Often cultivated for their foliage, showy flowers of intricate structure, and edible fruit.

caerulea

evgrn vine • ht to 30' or more • zones 8-10

blue passionflower

fragrant, screen, sun
Brazil to Argentina

Fast-growing, with leaves divided into narrow, finger-like segments. The spicily fragrant, blue and white flowers are 2-4" across. One of the hardiest of the evergreen passionflowers, it is root hardy to zone 6 with winter protection, and top hardy to about 10° F. Blossoms appear primarily in spring on the previous season's growth, so it often will not flower if the top growth is killed in winter. Does well in containers.

se US

A vigorous perennial vine with deeply 3-lobed leaves. Flowers are lavender and white, 2-3" across, of intricate structure and very showy. Very slow to begin growth in spring, but once started it grows rapidly. Flowering continues over a long period in summer. Fruit is about 2" long, egg-shaped, and edible when ripe. The flavor of the fruit is much like that of the tropical passionfruit. Prefers sandy soil and a sunny location. Needs a fairly long season to ripen fruit. A winter mulch is needed in colder areas, at least until the plants become well established. For fruit production, two or more should be planted.
