Green Alder is a native, cold-hardy shrub found in boreal forests, along slopes, and in open upland habitats. It fixes nitrogen in the soil, improving fertility and helping other plants grow, while its roots help stabilize slopes and disturbed ground. Fast to establish on poor soils, it is widely used in reclamation, restoration, and erosion control projects.

With its smooth grey bark and shiny green leaves, Green Alder often forms dense thickets that provide cover for birds and small mammals. Its seeds, buds, and catkins also supply food for wildlife. Green Alder is well suited for naturalization and ecological restoration.

Note: We use Green Alder for Alnus alnobetula subsp. crispa. This species is also known by many other common names, including Mountain Alder, Sitka Alder, and others. Please confirm the scientific name to ensure you are ordering the correct plant.

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.
