Eriogonum roseum is widespread and typically common; occasionally it will be locally abundant but only rarely can it be considered weedy. It occurs from southwestern Oregon south through much of California to northern Baja California Norte, Mexico. Morphologically this annual species approaches the perennial E. elongatum, and poorly prepared specimens sometimes are difficult to differentiate. A clear distinction between E. roseum and E. gracile appears to be consistently possible in the field, but some herbarium material can be difficult to assign. By and large, E. roseum is more robust and less branched than the decidedly more slender and graceful E. gracile. Seeds of Eriogonum roseum were pounded into a powder and either mixed with water and used as a beverage or eaten raw by the Kawaiisu people (M. L. Zigmond 1981).

Eriogonum pulchrum occurs as a series of scattered populations north of the Mogollon Rim from northeastern Mohave County, eastward into Apache, Coconino, and Navajo counties; it is found also in northern Yavapai County. It is clearly related to E. ericifolium but is morphologically more distinct from that species than E. thornei is from E. ericifolium. The recognition of E. pulchrum at species rank is a logical extension of the treatment given to Thorne’s wild buckwheat by L. M. Shultz (1998). The species is occasionally seen in cultivation.
