Douglas's Spirea or Hardhack is a native deciduous shrub of wet but well-drained habitats, growing from California to British Columbia. Forming potentially large thickets in moist sites, it may work well as an individual shrub. It is most distinguished by the pyramidal, rosy-colored, flowering stalks that appear in late spring.

The rounded leaves are shallowly serrated and pale to bluish-green, and one-to-three inches in length. Shrubs may reach six feet in height. The upright flower stalks reach six inches in length, each composed of small blooms with numerous stamens; the stamens give the plants a fuzzy appearance.

Tolerant of a variety of conditions, hardhack can grow in partial shade, relatively dry sites, or sunny locations. Once established, plants require minimal care.

These plants are grown from cuttings.
