 Physocarpus capitatus (Pursh) Kuntze – Pacific ninebark

This large, spreading shrub grows rapidly to 12,' with small, maple-like leaves and thin, shreddy bark. Some say there are nine layers of bark, leading to the name.

Small white flowers unfurl in a dense cluster of 3-5," like ready-made corsages for a summer gala.

In fall the leaves turn vivid shaded of red and orange.

Pacific Ninebark grows in sun or shade.

It likes moist sites and will tolerate seasonal flooding, as well as summer droughts.

It is at home from Alaska to California and is hardy between USDA zones 3-10.

It is considered to be poisonous by Natives.
