Pileostegia viburnoides

Evergreen climbing Hydrangea from China with long, lush, strappy leaves; will climb a big tree trunk over time and put on a showy bloom of white, frothy flower clusters in late summer that bees enjoy. Prefers rich, moist garden soil and bright shade.  Seems to grow vertically and doesn’t wander out and cover branches, so co-exists well with the tree it grows on.
