Red Alder

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.

Red Alder is a fast-growing deciduous tree native to western North America. Its fixes nitrogen, which enriches soils and supports the growth of surrounding plants. Ideal for sites with poor soil conditions, or areas disturbed by logging, construction or fire.
It provides shade in riparian areas, creating cover for fish. Its seeds and buds are eaten by birds and small mammals, while the foliage provides browse for wildlife. The catkins release clouds of pollen attracting bees and other insects.
The Red Alder gets its namesake from the rusty-red color the bark turns when bruised.
