Pacific ninebark or western ninebark (Physocarpus capitatus) is a shrub that is native to California and confined to western North America—from southern Alaska east to Montana and Utah, and south to southern California—in the redwood forest, chaparral, yellow pine forest, red fir forest and wetland-riparian communities. The plant gets its common name from its bark, which may peel showing several layers

It is a deciduous bush up to 8 feet tall, with round 3-to-5-inch clusters of white flowers having five petals and numerous red-tipped stamens, flowering May through July. The blossoms have been noted as being attractive to a large number of native bees. Also, small animals and birds find shelter in its branches. The leaves are lobed, about 1.2–5.5 inches long and broad, alternate, generally serrate, and remind me of small grape or currant leaves, though some say they are maple-like. They turn intense red to orange in the fall. The fruit is an inflated glossy red pod, which turns dry and brown and then splits open to release seeds.

Many nurseries recommend the plant not only for its delightful display of flowers and its showiness in fall, but also for the sculptural attractiveness the rest of the year. It grows best in moist environments, but it is drought-tolerant to a degree.

Earth Day is April 22, but at least one organization is proposing a week's worth of activities.
