Ceanothus integerrimus (Deerbrush)

Deerbrush


Filling the air with its sweet, spicy honey scent, Ceanothus integerrimus (Deerbrush) is a variable shrub in form. In some areas, it may be a deciduous tree-like shrub with an open ascending to erect branch habit. In others, it can be evergreen or semi-semi-evergreen and form a flattened mound. Its glossy green leaves are thin and egg-shaped, up to 3 in. long (7 cm). In late spring to mid-summer, depending on locations, a profusion of feathery clusters, 6 in. long (15 cm), packed with small, pleasantly fragrant flowers are borne at the tips of flexible twigs. The flowers are usually white, but blue or even pink specimens can be found. Bees and butterflies are attracted to the flowers. The blossoms give way to a sticky capsule containing small seeds. Native to the western United States, Deerbrush grows in a wide range of habitats, including chaparral mountain shrub regions, hardwood forests of the west, and fir, spruce, and Ponderosa Pine communities being most abundant in chaparral in California. Due to its nitrogen-fixing capabilities, it is often included in restoration efforts in its native range. Tolerant of summer watering in well-drained soils, Deerbrush performs best in montane landscapes. Excellent filler on slopes, Deerbrush is striking in mass or as a specimen.

  • Grows up to 3-13 ft. tall (90-390 cm) and 7 ft. wide (210 cm).
  • Performs best in light, well-drained soils in full sun to light shade. Tolerates decomposed granite or clay soils. Drought tolerant.
  • Excellent plant for bank stabilization, bird gardens, butterfly gardens, and bee gardens.
  • No serious pest or disease issues.
  • Prune out rangy branches in late summer to maintain a neat appearance and promote compact growth.
  • Propagate by seed (after scarification and stratification) or cuttings.
  • Native to the western United States, in Arizona, New Mexico, California, Oregon, and Washington.
