Arrowwood
Sitka Alder

Arrowwood is a cold hardy, reliable, and vigorous shrub that can easily grow on difficult sites. Featuring an upright, rounded, and multi-stemmed form, this shrub produces creamy white flowers against a backdrop of deep green, serrated foliage.

The flowers give way to dark, blue berries that will attract wildlife to your yard. Depending on the plant, Arrowwood's striking fall color can range from yellow, red to reddish-purple.

Many use Arrowwood for naturalization or mass planting projects but, more commonly, you'll see this simple yet elegant shrub as a shrub border or planted on its own.

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.
