Ninebark (Physocarpus opulifolius) is a striking shrub with long, graceful, arching canes and pink-white flowers in early summer that attract birds and butterflies. It grows 5-8 feet tall and 4-6 feet wide and does well in full sun to half-shade. An excellent accent plant that tolerates drought well. This plant is labeled 'Diabolo' Ninebark but probably is not, as 'Diabolo' has deep reddish-purple leaves.
