Hedge Rose
Mountain Alder

Hedge Rose is a long-lived, fast-growing shrub. It bears similar flowers to the Alberta Wild Rose. Birds will love its deep red rose hips. Hedge Rose will thrive in a wide variety of soils and is a tall rose forming a useful hedge.

Excellent for shelterbelts, ecobuffers, and wildlife habitat plantings. Continuous flowering makes it attractive to pollinators. Many song and game birds utilize this tree for food and habitat.

In use since the early 1900s, this hybrid was originally developed at the PFRA's Indian Head Agroforestry Center.

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.
