PhenologyBlooms mainly from May to July, and sporadically later; fruits from July to October.
IdentificationThis is a very familiar and popular native wildflower, known to nearly everyone. It is an herbaceous, climbing or trailing vine that often reaches 20-25 feet long. The alternate leaves are very distinctive, having 3 leaflets and entire margins; each leaflet is about 2 inches long and 3/4-inch wide. The huge and complicated-looking flowers are axillary, opposite a leaf; each has a spread of almost 3 inches across, with white to lavender petals. The corona has numerous thread-like filaments, looking like white and purple strings coming off the center of the flower; see photos for a better understanding of the flower structure. The fleshy green fruit is about 2 inches long, ovoid in shape, and edible to humans. This species is a valuable host plant for several showy butterflies, such as Gulf and Variegated fritillaries, and Zebra Longwings farther south.
