We found this new climber a few years ago and we love it. The young shoots boast tons of tendrils just waiting to climb and cling to your favorite trellis. Leaves are ovate and glossy. We find the older the plant, the larger the leaves. Blooms are yellowish-white and form more panicle florets with ups to a dozen petals. Not as hardy as regular climbing hydrangeas so guessing a 7b zone. Climbs and climbs!
