|discussion=<p>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.</p><!--
