This climbing perennial vine flowers from June through August. It spreads by rooting at the nodes of the vines, and also by seed dispersal. The vine can grow up to 30 m in length when growing along the ground.
The compound leaves are composed of 3 to 7 leaflets, usually 5. The leaflets have toothed margins, and turn red to maroon in the fall. Each ovate leaflet grows on long petioles, and can grow from 4-15 cm long.
This plant is often confused with poison ivy, but can be distinguished by its 5 leaflets that originate from a single point.
