About
Physocarpus opulifolius, the common ninebark, is a vigorous, deciduous shrub to around 3 m with layered, flaking, attractive bark and an upright, arching habit. Dense, rounded clusters of small, white flowers tinted pink are produced along the stems in early summer, followed by reddish-green seed pods. Broadly ovate, toothed, three-lobed leaves colour well in autumn. A rewarding and reliable shrub for a sunny or partly shaded garden.
