climbing hydrangea

Climbing hydrangea (Hydrangea anomala, Hydrangeaceae) is a deciduous woody climber from the Himalayas and China, reaching 30 to 40 feet by attaching to surfaces via aerial rootlets. White, fragrant flowers appear in flat clusters from May to June.

Climbing hydrangea grows in part to full shade with moderate water needs, hardy in Zones 5 to 8. It tolerates rabbit browse, drought, and heavy shade. No cultivars are documented.
