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
Schizophragma hydrangeoides, commonly called 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.
Genus name comes from the Latin schizein meaning to split and achyron meaning chaff.
Specific epithet means like the genus Hydrangea, which it resembles.
Problems
No serious insect or disease problems. Often slow to establish.
Uses
Use in shady areas to climb walls, arbors or trees. May also be sprawled over low walls or rocks.
