It is native to regions including Greenland, Labrador, Newfoundland, and various Canadian provinces, as well as parts of South America and Europe. The species was first published in 1817. A lectotype was designated by Egorova, but due to sterility, a fertile specimen from the Celsius herbarium was later designated as an epitype by Kukkonen.
