In North America it occurs throughout northern regions, including northern sections of the United States and most all of Canada, its range continuing to Greenland. It is widespread throughout the Canadian Arctic Islands. The grass occurs in a variety of Arctic and alpine habitat types, as well as many types of mountainous habitat in regions farther south. It is a perennial grass forming clumps of erect stems ranging in height from just a few centimeters to over one meter.
