Northern Red Currant
Mountain Alder

The Northern Red Currant is also known as the Swamp Red currant due to its preference for moist soil. As long as the soil is wet, this shrub can live in any degree of sunlight.

The currant itself is a bright red-purple berry enjoyed by many animals and some people for its sour flavour, similar to garden red currants. The flowers of this shrub are tiny and red or greenish-purple.

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.
