Greyleaf Willow

About Greyleaf Willow in Alberta

Greyleaf willow is a native Alberta willow best treated as part of the broad and variable Salix glauca complex rather than as one narrow single-form shrub. In Alberta it belongs mainly to northern, foothill, mountain, subalpine, and alpine shrubland settings, where gray-toned, hairy foliage and cold-site habitat are more important than ornamental or urban use. For Ancient Roots Alberta, it matters most in intact native cold-region shrub systems and willow communities that still reflect upland, northern, or alpine-subalpine ecological continuity.

Identification: Leaves are usually narrowly elliptic, elliptic, oblanceolate, or obovate, often with entire margins. Their strongest general field character is the gray-green to grayish tone produced by dense hairs and glaucous character, especially beneath. This soft muted foliage is one of the quickest ways to recognize the species complex in the field.

Alberta range and habitat: Greyleaf willow is native in Alberta and is best treated as a northern, foothill, mountain, subalpine, and alpine willow rather than as a prairie-town or urban species. It belongs to colder natural landscapes and upland or northern shrub systems.
