Passion Flower 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 is native to the Southeastern U.S. and is easily grown in average, medium, well-drained soils in full sun to part shade. In its natural habitat it is found along stream banks, roadsides, woodland edges, meadows and pastures. Although it is tolerant of drought, a loose mulch helps to keep the roots cool. It spreads by root suckers to cover large areas in optimum growing conditions. This is the hardiest of the passion flowers and does not have to climb in order to flower. If a bushy growth habit is preferred, pinch the vines back after the first growing season.

Maypop is a common name for this vine, relating to the loud popping sound made when the fruits are stepped on. This plant is moderately resistant to damage from deer. The showy flowers and edible fruit make it an excellent choice for an arbor, pergola, trellis, fence or wall near a patio where it can be enjoyed.
