Hydrangea anomala subsp. petiolaris var. minor BSWJ 5991
Collected by Crug Farm in the high mountains of Yakushima, this is a rare variety of climbing Hydrangea that is much reduced in size. This self-clinging vine has tiny dark-hued terrestrial leaves as it clambers about on the ground and over boulders but once it finds a likely tree trunk, it will climb to 10' or more with larger leaves and white lace-cap flowers in early summer. If you are looking for a smaller climbing Hydrangea, look no further.
