Green Alder
Black Elderberry

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.

Black Elderberry is a deciduous shrub native to eastern North America. You can plant this shrub in moist areas and it will help stabilize your soil. You can also use it on rural properties anywhere you'd use a lilac.

Black Elderberries are considered to be partially self-pollinating. So while they will still produce some berries without cross-pollination, planting with another variety will increase yields. Consider planting with Ranch Elderberry or Bob Gordon Elderberry.

Warning: the seeds, stems, leaves, roots, and uncooked berries of the Black Elderberry are poisonous to humans when eaten in quantity. You should cook the berries to make them safe for human consumption.
