Passion Vine (Passiflora), evergreen vine spreading rapidly to 20 ft. or more, climbs by tendrils, needs support, gorgeous flowers in pink, red, orange, white, blue and purple almost all year, best in full sun, drought tolerant, prune to control, very attractive to hummingbirds.
Most passion vines are South American natives. All climb by tendrils 20 to 30 ft. Foliage is typically rich green. Plants bloom during warm weather. Many species produce edible fruit as a bonus. Train passion vines on trellises or walls for their vigor and bright, showy flowers; or use as a soil-holding bank cover. Vigorous, likely to overgrow and tangle; require rigorous thinning and untangling. Winter and early spring are best times for major pruning, but you can thin excess new growth at any time in the growing season. Tolerate many soil types.
