Taxonomic Notes

Varieties: none


P. incarnata is a perennial forb/herb/vine of the Passifloraceae family native to North America. [1]


P. incarnata is found in the southeastern corner of the United States. [1]



P. incarnata proliferates in roadsides, fencerows, thickets, and fields. [2] Specimens have been collected from pine flatwoods, fields, roadside, live oak hammock, old field, sandysoils, fence row, open pasture, waste area, old brick wall, and shore of lake. [3]


P. incarnata has been observed flowering April through August and in October. [4] This plant is a smooth vine with finely hairy stems climbing to a height of 10 to 30 feet. Its smooth or somewhat hairy leaves, 3 to 5 inches broad, consist of three oval or egg-shaped lobes with finely toothed margins. The flowers, which appear from May to July, are solitary and are characterized by a lavender and purple or pink and purple fringe 1 1/2 to 2 inches broad. The plant produces smooth, yellow, many-seeded, edible fruit almost 2 inches long, called maypops. [5]

Seed dispersal

This species is thought to be dispersed by consumption by vertebrates. [6]

Conservation and Management

P. incarnata is listed as rare by the Indiana Department of Natural Resources Division of Nature Preserves, as threatened by the Ohio Department of Natural Resources Division of Natural Areas and Preserves, and as a weedy or invasive species by the University Press of Kentucky and the Southern Weed Science Society.
