It has a very local distribution, confined to open ground and mountain summit plateaux above 1,250 metres that are sufficiently exposed to be kept snow-free. Its native distribution includes Iceland, Svalbard, northern Norway and Scottish mountains and mountains of Western North America and the Kamchatka peninsula.
