Physocarpus capitatus

Physocarpus capitatus

''Physocarpus capitatus'', commonly called Pacific ninebark or tall ninebark, is a species of ''Physocarpus'' native to western North America from southern Alaska east to Montana and Utah, and south to southern California.

It is a dense deciduous shrub growing to 1–2.5 metres tall. The name comes from the appearance of the bark, which is flaky, peeling away in many layers. The shrub has distinctive maple-like lobed leaves 3–14 centimetres long and broad, and clusters of small white flowers with five petals and numerous red-tipped stamens. The unique fruit is an inflated glossy red pod which turns dry and brown and then splits open to release seeds.

It is often found in wetlands, but also forms thickets along rivers and in moist forest habitats. While it grows most robustly in wet environments, it is drought-tolerant to a degree and is a popular California garden plant.
