The petals and sepals subtend a fringe of wavy or crimped, hair-like segments. The pistil and stamens are also showy. Three-lobed, deciduous leaves are dark-green above and whitish below. The fruit is a large, orange-yellow berry with edible pulp. Like some other passion vines, Maypop spreads by root suckers.
