Gaultheria shallon (gol-THEER-ee-uh SHAL-lon)

Family: Ericaceae Unknown Groundcover

Salal is an evergreen shrub in the heather family that is native to western North America and will develop thickets that make a good bird habitat. It is found as an understory shrub in the coastal NW at lower elevations. The form is erect to prostrate and stems root if growing on the ground. The leathery, glossy green oval leaves are evergreen and are used by florists in flower arrangements. The clusters of drooping urn-shaped white-to-pinkish flowers appear in spring to early summer and are followed by purple berries that are eaten by birds. This shrub grows in partial to full shade in moist acidic soils but is adaptable to other sites. It may not be a good choice for the east due to our very different growing conditions. Use as a ground cover in shady to partly shady naturalized woodland sites. Insects, Diseases, and Other Plant Problems: No significant problems.
