This has a broad northern and western range, with local extension down the southern Appalachians to n. Va. Records from Tenn. (Ch) and N.C. (W) are only old or obscure. It is closely related to the Eurasian species, S. galericulata L. In Ky. there is only one verified record: a coll. from ROCK (KY-Agr.), 8 Jul 1915, stating "Conway, Ky." but with no collector. The plant has also been reported by Hussey (1876) from BARR or EDMO, and by Greenwell (1935) from NELS.
