Black Elderberry
Mountain Alder

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.

Mountain Alder is a native cold-hardy shrub or small tree often found along streams and in moist forested habitats. Its nitrogen-fixing ability enriches soils and supports surrounding vegetation, while its extensive root system helps stabilize streambanks and slopes. The fast growth rate allows it to establish quickly on disturbed sites, making it especially valuable in reclamation, restoration, and erosion control projects.

Often forming dense thickets, Mountain Alder enhances habitat quality in riparian and upland areas. It provides food and cover for various wildlife, including birds and small mammals. Recognized as an important species for soil and water conservation, it is well suited for riparian planting, naturalization, and ecological restoration.

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