Green Alder
Aldara Hazelnut

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.

Aldara Hazelnut is a northern hybrid selection noted for its superior nut quality, disease resistance, and cold hardiness.

It is great for attracting wildlife with the added bonus of edible nuts that can be eaten fresh or used in baking. Pair with another Aldara or Andrew Hazelnut for cross pollination to occur.

Aldara and Andrew Hazelnut are currently the hardiest and most reliable nut varieties available for the Canadian prairies.

Note: You want more than one hazelnut to improve yields.
