Hydrangea anomala subsp. Petiolaris
Climbing Hydrangea
This large vining shrub is native to Japan and Korea.
It grows best in partial or full shade and in rich, moist soil.
If allowed to climb, it clings and twines to a height of 40 feet.
Without structure, it can become a groundcover shrub.
Climbing hydrangea blooms in late spring with fragrant green and white flower clusters.
