Silverberry (Wolf Willow)
Sitka Alder

Silverberry (also known as Wolf Willow) is a common native North American shrub. This beautiful ornamental plant has characteristic silver leaves and fragrant yellow flowers.

Its silver berries remain on the branches through the winter. Silverberry is cold hardy and has some ability as a nitrogen fixer. It can grow on dry to moist sandy/gravel soils. This plant is very low maintenance.

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.
