Closely related to hydrangeas and has attractive deep green, glossy, oval leaves that narrow to a pointed tip. Flowers are fragrant, soft and puffy looking but not terribly showy. Vigorous vine that climbs by aerial rootlets.  Native to low woods, swamps and river banks, especially in areas that are periodically flooded.  Even though it can be used as either a trailing groundcover or a climber, it will only bloom when climbing and only blooms on new wood.  Too vigorous to mix with other groundcovers or herbaceous plants.  Cultivars available.
