It is the state flower of Washington. It is an evergreen shrub growing up to 2–9 m (7–30 ft) tall. The leaves, retained for 2–3 years, are 7–23 cm (3–9 in) long and 3–7 cm (1–3 in) broad. The flowers are 2.8–4 cm (1.1–1.6 in) long, with five lobes on the corolla; color is usually pink, although variants exist. The northern limit of its range is somewhat north of the border between Canada and the United States in British Columbia. It is found as far south as Monterey Bay in California.[5] It is widely distributed in the Coast Mountains and Cascade Range.

It is mostly coastal in distribution but extends its range eastward to locations in the Cascade Mountains in Oregon, Washington and British Columbia.
