Sitka Alder
Northern Bush Honeysuckle

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.

The Northern Bush Honeysuckle is a small, dense, deciduous shrub. The trumpet-like yellow flowers bloom late spring to early summer. Dark green leaves turn yellow then red in the fall. The flower nectar has a sweet honey taste that can be sucked out of the flower.

Because of its aggressive suckering habit, the Northern Bush Honeysuckle makes a great hedge, shrub border, or thicket in a woodland garden.
