Mountain Ninebark (Physocarpus monogynus) is a very attractive native shrub that maintains a 3-4' mound and provides excellent long-season interest. Mountain Ninebark features attractive green foliage that emerges in the spring, corymb-shaped groups of white or light pink flowers in the early summer that give way to red seedheads, red and orange leaf color in the fall, and bark that peels in papery strips to reveal chocolate-covered bark beneath for winter interest. Mountain Ninebark is excellent for traditional beds and borders, dry shade or woodland gardens, or for use as a low hedge. Ninebarks are usually very tolerant of urban pollution.
