Passionflower Passiflora incarnata

Passionflower is a rapidly growing, trailing or climbing perennial or herbaceous perennial. It is a member of the passion vine family (Passifloraceae). It is native to the southeastern and south-central parts of the United States, as well as Bermuda. The genus name, Passiflora, relates to the crucifixion of Jesus Christ. In the 15th to 16th century, Roman Catholic priests in Latin America used parts of the flower to symbolize the Passion of Christ. The species epithet is Latin for “flesh-colored,” but the reference is obscure.

Passionflower is a rapid-growing, trailing vine that climbs by axillary tendrils. It is woody in warm winter climates but dies to the ground in cold winter climates. It grows in average-fertility, well-drained soils in full sun to part shade. Although this vine is tolerant of drought, a loose mulch can help to keep the roots cool. Under optimum growing conditions it spreads by root suckers to cover large areas. This is the hardiest of the passionflower vines, and it does not have to climb in order to produce flowers. If a bushy growth habit is preferred, pinch the vines back after the first growing season.

This plant is moderately resistant to damage from deer. The showy flowers and edible fruit make it an excellent choice for an edible, an arbor, pergola, trellis, fence or wall near a patio, where its showy flowers can be enjoyed. This plant has an extreme flammability rating and should not be planted within the defensible space of your home. Select plants with a low flammability rating for the sites nearest your home.  

Insects, Diseases, or Other Plant Problems:  No serious insect or disease problems. The roots can spread aggressively, and in poorly drained wet soils root rot can occur, especially in the winter.
