Wild Yam is a perennial vine found in moist forests and woodlands in eastern Canada and the U.S.A. Individual plants are either male or female. The flowers on a male are panicles and appear in clusters of 1 to 3 along the branches. The tiny flowers are 1/8" across, each having 6 white-green or yellow-green tepals and 6 fertile stamens. Female flowers appear on 3-9" racemes of 5-15 flowers that develop from the leaf axils. They too are tiny flowers, 1/8" in size. The female flowers are replaced by 1" capsules that contain 1-2 seeds.
This plant is at its best when grown in full sun. It will take some shade, but will not produce flowers or seeds.
