Although P. incarnata is the hardiest of the passion flowers, it is not reliably winter hardy throughout USDA Zone 5 and may not survive extremely cold winters therein. In the St. Louis area, it is best to plant this vine in a protected area that is sheltered by a wall, garage or other structure.
Passiflora incarnata is a rapid-growing, tendril-climbing vine which is woody in warm winter climates and herbaceous (dies to the ground) in cold winter climates.

Features three-lobed, dark green leaves and showy, 2.5" diameter, fringed flowers having white petals and sepals and a central crown of pinkish-purple filaments. Flowers bloom in summer and are fragrant. Fleshy, egg-shaped, edible fruits called maypops appear in July and mature to a yellowish color in fall. Ripened maypops can be eaten fresh off the vine or made into jelly. Maypop is also a common name for this vine. Maypop name refers to the loud popping sound made when fruits are stepped on.
