Hydrangea anomala petiolaris
Climbing Hydrangea – 2004 Plant of Merit

Climbing by clinging aerial rootlets to as much as 30-50 feet, this vigorous woody vine will easily grow up a variety of structures including arbors, fences, trunks of large trees or walls. It will also sprawl as a ground cover. It features heart-shaped, serrate, dark green leaves with little fall color and a late spring bloom of white flowers in flattened, lacecap-type clusters. Lateral branching gives the foliage a somewhat tiered appearance. Exfoliating reddish-brown bark on mature vines can be quite attractive in winter. Thrives in moist shady locations. Height: 30 to 50 feet and spread: 5 to 6 feet
