Decumaria barbara L.
Decumaria, Climbing hydrangea, Woodvamp
USDA Symbol: DEBA4
USDA Native Status: Native to U.S.
A woody vine to 30 ft., attaching by rootlets, with smooth, shiny, round to oval, deciduous leaves and fragrant flowers in flat-topped terminal clusters. Individual flowers are small and pale white with numerous stamens, held 1 to 2 feet from climbing surface. The subsequent fruiting capsules are urn-shaped.
Unlike some forest vines, it maintains full leaf coverage from shady ground to sunny canopy, with glossy, dark green foliage providing an airy backdrop to the ethereal white blooms. Though it can be used as both a trailing groundcover and a climber, it will only bloom when climbing, and then only on new wood. Great for moist Southeastern gardens with seasonal flooding.
