ILPARW (southeast Pennsylvania - Zone 6b) on May 10, 2019 12:31 PM concerning plant:
I've only seen one specimen of this species from Japan. (There is also a Chinese Hydrangea-vine that is very similar with larger leaves and flower clusters from China, of course.) This specimen has climbed way up a full-grown Northern Red Oak tree in southeast Pennsylvania in the front yard of my biggest customer who is a plant enthusiast, having a number of such uncommon plants. This woody vine (liana) climbs by root-like holdfasts. I have seen the Climbing Hydrangea (H. anomala petiolaris) sold at some larger, diverse. conventional nurseries, but not this one. It is offered by some specialty nurseries.
