Physocarpus, commonly called Ninebark, is a genus of about ten species of flowering plants in the family Rosaceae, native to North America (most of the species) and northeastern Asia (one species).
They are deciduous shrubs growing to 1-3 m tall. The name comes from the appearance of the bark, which is flaky, peeling away in many layers. The leaves are maple-like, palmately lobed, 3-15 cm long and broad, with an irregularly serrated margin. The flowers are white with five petals and numerous stamens, produced in corymbs. The fruit is a cluster of inflated follicles, which turn dry and brown and then split open to release the seeds.
