Labrador willow

Salix argyrocarpa grows as a shrub and can sometimes form clones by layering. The branches are red to brown in color with little to no hair. The leaves generally lack functioning stipules and are narrow and elliptic, oblong, or oblanceolate in shape, measuring 25–65 by 7–15 millimetres (0.98 in–2.56 in × 0.28 in–0.59 in). The catkins flower in June to early August as the leaves emerge, and the capsules measure 2–4 millimetres (0.079–0.157 in).

Salix argyrocarpa grows naturally in Newfoundland and Labrador, Quebec, Nunavut (on the Belcher Islands), Maine, and New Hampshire. It inhabits wet areas, including floodplains, edges of lakes and streams, and snowbeds, as well as subarctic and subalpine habitats. It prefers granitic, sandstone, and limestone soils.
