About

Salix arctica, the Arctic willow, is a tiny creeping willow (family Salicaceae). It is adapted to survive in Arctic conditions, specifically tundras.

Where it grows

The Arctic willow grows in tundra and rocky moorland, and is the northernmost woody plant in the world, occurring far above the tree line to the northern limit of land on the north coast of Greenland. Its distribution is circumpolar. It occurs in Canada in the mainland northern territories and in the Arctic Archipelago all the way up to Ellesmere Island alongside Greenland, and in northern Quebec and Labrador, as well as in northern Iceland, Fennoscandia, northern Russia and northern Alaska.

Uses

Both the Inuit and the Gwich’in make use of this willow. Twigs are used as fuel, while the decayed flowers (suputiit) are mixed with moss and used as wicking in the kudlik. The plant was used for several medicinal purposes, such as relieving toothache, helping to stop bleeding, curing diarrhoea and indigestion, and as a poultice on wounds.
