This widespread species has a discontinuous circumpolar distribution (Hultén, Circumpol. II, p. 304 and map 295). It has been frequently introduced into N. America (locally Mexico), S. America and S. Africa. The distribution, especially in Asia, is incompletely known. In western N. America a native taxon, subsp. humile (Hook.) Hult., also occurs.
