Sitka Alder
Gray Dogwood

Sitka Alder is a native deciduous shrub or small tree that often forms dense thickets. Its extensive root system stabilizes slopes and streambanks. Nitrogen-fixing capabilities and nutrient-rich leaf litter improve soil fertility, creating better growing conditions for surrounding plants. These qualities make it especially effective in disturbed or erosion-prone sites.

Often found in moist, high-elevation mountain environments, Sitka Alder also enhances habitat by providing cover and structure in both riparian and upland areas. Birds and small mammals utilize it for nesting, and its seeds serve as a food source.

Note: We use Sitka Alder for Alnus alnobetula subsp. sinuata. This species is also known by many other common names, including Mountain Alder, Green Alder, and others. Please confirm the scientific name to ensure you are ordering the correct plant.

Gray dogwood is a thicket-forming, deciduous shrub with greenish-white blossoms in open, terminal clusters. Young twigs are red and the fruit pedicels remain conspicuously red into late fall and early winter.

Fruit itself is a white, 1/4 in. drupe that usually does not remain on the shrub for long.

Great for naturalizing wild areas, this shrub attracts birds and other wildlife.
