In North America, it can be found in Alaska, Greenland, the Canadian Arctic, and the Rockies, Cascades, and Sierra Nevada as far south as Arizona and New Mexico.[4][5] In Eurasia, it is widespread across European and Asiatic Russia[6] and also grows in Scandinavia and in the mountains of central Europe (Carpathians, Alps, etc.)[7][8][9]
