Passionflower (Passiflora incarnata, the maypop) is a fast-growing trailing or climbing perennial vine that grows in USDA zones 7B to 11, needs full sun for the best flowering and needs regular pruning to stay in bounds. Clemson describes it as a fast-growing vine native to the Southeast. NC State says it is woody in warm winters but dies to the ground in cold ones, so it behaves like a perennial vine over a wide range of zones. This guide covers the ornamental Passiflora incarnata.

Pruning and spread
UF/IFAS says regular pruning is needed to keep passionflower in check. NC State says that if you prefer a bushy habit, pinch the vines back after the first growing season. It also says the plant spreads by root suckers under good conditions.
Bloom time
UF/IFAS EDIS says flowers appear in summer and early fall, and each flower lasts about a day. Gardening Solutions says the same about the day-long bloom.
Grow these next
Mandevilla is a climbing vine that Clemson says comes indoors before the first freeze in most of the country. Bougainvillea is another frost-sensitive plant for a sunny spot. The tropical flowers collection compares the group.
