Western Snowberry

Like the Common Snowberry, the Western Snowberry is a small shrub with pink flowers useful for feeding livestock and preventing erosion. Unlike the common species, however, the Western Snowberry is much more suited to wet conditions, capable of persevering through poor soil drainage and occasional flooding.

After the Snowberry's flowers have bloomed, it produces berries which often last on the plant through winter. These berries are toxic to humans, but livestock and local wildlife love them! Those hoping to attract wildlife to their property can plant Snowberry and expect to see animals foraging on it much later in the year than other plants.

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.
