Oak-leaved hydrangea

Oak-leaved hydrangea is a shrub for all seasons. The large leaves resemble oak leaves and are deep green and sometimes glossy.  They turn a deep burgundy in fall and sometimes can persist into winter. The large cone-shaped flower clusters open white and eventually turn a purplish-pink. Older bark is cinnamon brown color and peels to create a texture that makes this plant interesting even when the leaves are gone.
