During recent decades, this western species of subalkaline clays has spread to disturbed areas as far east as Ind., Ohio and Ky. (FNA 4; NS; A. Cusick, pers. comm.). It flowers and fruits relatively early for a chenopod, in Apr-May, and it has often been found on compacted soils in fairgrounds and similar sites, before mowing for the annual summer events. The only Ky. record so far is a coll. from a muddy horse show ring at the fairgrounds of OLDH: A. Cusick #36043, 2002 Apr16 (Miami University herbarium).
