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.
