This small cottony-looking semi-evergreen shrub has a wide distribution across western North America, where it occurs from 2000 to 8000 feet. Its narrow leaves are covered with fine white hairs, giving the plant a woolly appearance. Male and female flowers are inconspicuous, and are produced on different plants. The female plants produce fluffy seed heads that are stunning when backlit by the sun. Plant in full sun and very well-drained soils. Prune heavily in early spring to maintain a dense form.
