Ninebarks are so named because of their peeling bark, which is many layers deep. These deciduous shrubs resemble spirea and are closely related to it, bearing round clusters of tiny white or pinkish flowers in spring or early summer. All have medium green leaves with lobed edges. Prune plants as needed after bloom; rejuvenate by cutting old stems to the ground.Physocarpus capitatus
