General Culture:
Best grown in rich, medium moisture, well-drained soil in part shade to full shade. Prune in late winter to early spring. A single plant will eventually grow 30' or more wide, though for quick coverage of a wall, space 6-9' apart.
Noteworthy Characteristics:
Japanese hydrangea vine is a deciduous, woody-stemmed, climbing vine which is valued for its toothed, heart-shaped, deep green leaves (3-5" long) and large, flat-topped, lace cap hydrangea-like clusters (8-10" across) of white flowers which bloom in early summer. Foliage turns yellow in fall. Attaches to and grows up flat vertical surfaces such as masonry walls by stem-borne adhesive rootlets. Reddish-brown stems provide some interest in winter.
Problems:
No serious insect or disease problems. Often slow to establish.
Uses:
Use in shaded areas to climb a masonry wall or tree or to sprawl over low walls or rocks.
