Found in the northern reaches of the Tallgrass region on rich woodland soils. Flowers bloom from May through June. Thesel vines grow up to 7 feet long, thornless (uncharacteristic for this genus) and will cling to fences, trees and bushes by twin tendrils that emerge from the leaf axils. A single plant will produce either male or female flowers, but not both. Anywhere from 12 - 85 tiny green-white flowers form in a ball at the end of a flattened, 4 to 9 inch long flower stalk. The flowers have the odor of rotting flesh which attracts the insects necessary for pollination. The female flowers produce an edible berry, blue-black in color when ripe.
