Green Alder
Gray Dogwood

Green Alder is a native, cold-hardy shrub found in boreal forests, along slopes, and in open upland habitats. It fixes nitrogen in the soil, improving fertility and helping other plants grow, while its roots help stabilize slopes and disturbed ground. Fast to establish on poor soils, it is widely used in reclamation, restoration, and erosion control projects.

With its smooth grey bark and shiny green leaves, Green Alder often forms dense thickets that provide cover for birds and small mammals. Its seeds, buds, and catkins also supply food for wildlife. Green Alder is well suited for naturalization and ecological restoration.

Note: We use Green Alder for Alnus alnobetula subsp. crispa. This species is also known by many other common names, including Mountain Alder, Sitka 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.
