Wild Yam
Dioscorea villosa /Yam Family

The flowers of this vine are small and barely noticible. The whorled, heart-shaped leaves are the most attractive feature. Look for the interesting, 3-winged fruits in the fall.

I call this vine the "Birth Control Pill Vine." It is related to the Mexican Yam, which was the source of the original steriods used in early birth control pills.
Perennial
