Common ninebark is a native shrub with an upright, spreading habit. The plant gets its name from the fact that its bark peels in thin strips on its long, thin branches.
It has pretty, lobed leaves and clusters of white-pink flowers in May and June. It is often found in nature along waterways, streambanks and forest edges, so it benefits from regular moisture periodically.
Common ninebark has taken several years to establish as a native shrub at the Xeriscape Demonstration Garden. It seems to benefit from partial shade and regular moisture.
Prune out older stems periodically to keep the shrub attractive.
