Variety longifolia is widespread in the United States from the prairie states westward. In the westernmost states, its distribution is restricted (Lincoln County, Nevada; Siskiyou County, California; Baker, Malheur, and Wallowa counties in Oregon; Asotin County, Washington), and these plants are slightly smaller than in the rest of the range. It reportedly does not persist in British Columbia.
