This showy white "poppy-mallow" (a perennial) occurs mostly in the central Great Plains, and it may be native east to s. Ill. and w. Tenn. (Ch, PL). In Ky. the only certain record is a coll. of A. Michaux (Paris) from BARR or ALLE in 1795: "barren oaks endica de Big Barren River" (M); this is the type coll. for the species. There is also a coll. of C.W. Short (PH) but without data. The species is easy to propagate, and it should be used along roadsides and other suitable sites in w. Ky.
