An easily grown plant, Passion Flower look absolutely stunning in the garden or inside as a year-round houseplant. The Purple Granadilla is a vigorous and free flowering deciduous climbing perennial vine which grows up to 20 feet long at maturity. Blooming from late May through October, its beautifully intricate purple and white fragrant flowers are approximately 3-4" across and are followed by smooth, round 2 inch fruits that are edible and turn yellow when ripe. Although classed as half-hardy, Passion Flower can survive winters even in zone 6 when it has the shelter of a south facing wall.
