Schizophragma

Climbing hydrangea is a deciduous vine which climbs using suction roots, completely covering its support. The leaves are attractively heart-shaped, with toothed edges. The vine flowers white and pink in midsummer, somewhat resembling those of the Japanese climbing hydrangea, Hydrangea anomala subsp. petiolaris. The easiest distinguishing feature is that this Japanese has an outer ring of three to five sterile flowers, whereas in Schizophragma hydrangeoides there is only a single large one.
