Passionflower

Passiflora incarnata · Vine

Passionflower is a fast-growing vine, hardy in USDA zones 5-9, that matures to about 6–8 ft × 3–6 ft. It does best in full sun and part shade with medium water needs in well-drained, moist and occasionally-dry soil. Expect blue, pink and purple blooms in summer and fall. It attracts bees, butterflies and hummingbirds, stands up well to deer, drought and heat and grows happily in containers.
