Leaves grow in clusters of three with the middle leaf being slightly bigger than the two on either side. The leaves have veins that are opposite one another, growing upward in V-shaped patterns. Leaves start out reddish in spring, then become a shiny green in summer before turning various shades of red, orange, and yellow in fall. Plants produce small, waxy white berries in late summer that turn red in fall. As the vines age, the stems become woody and put out distinctive “hairy” root growths.
