Physocarpus opulifolius

Common Ninebark

Ninebark is a hardy deciduous shrub in the rose family that is native to central and eastern North America. In late spring and early summer, it produces attractive clusters of white to soft pink flowers, adding seasonal interest to the landscape. Its name comes from its distinctive exfoliating bark, which peels in layers as the plant matures.

This versatile shrub naturally grows in a variety of environments, including rocky slopes, stream banks, and moist woodland thickets. Ninebark is highly adaptable and thrives in slightly acidic, well-drained soils ranging from dry to moderately moist conditions. It performs best in full sun to partial shade and can be pruned back during winter to encourage vigorous new growth and maintain a healthy, rejuvenated appearance.
