Sitka Alder
Red Osier 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.

Red Osier Dogwood is a small deciduous shrub that features deep red stems and twigs year-round, with creamy white flowers in the spring. This shrub will add a nice pop of color to your yard.

Red Osier Dogwood is an excellent soil stabilizer. It is fast growing and becomes drought tolerant once well established.
