Woodside Buckwheat

Eriogonum tumulosum (Barneby) Reveal

Comments

provided by eFloras
Eriogonum tumulosum is infrequent in Duchesne, Emery, eastern Sevier, and Uintah counties, Utah, and in western Moffat County, Colorado. It is often confused with Parthenium ligulatum (M. E. Jones) Barneby (Asteraceae); they grow together and both form dense hummock-like mats. Woodside wild buckwheat is seen infrequently in rock gardens.
