Eriogonum umbellatum
Sulfur Flower
Polygonaceae
Perennials, Shrubs
ERIOGONUMIndividual blossoms are tiny but grow in long-stemmed or branched clusters—usually domed, flattish, or ball-like. Flowers age to an attractive tan or reddish brown and persist for a long time; good in dried arrangements. Flowers attract butterflies; birds enjoy the seeds. Grow best in well-drained, loose, gravelly soil. Useful for covering dry banks, massing among rocks; smaller forms make good specimens in rock gardens.
Eriogonum umbellatumNative to mountains of the western United States. Plants grow to timberline and above. Low, broad mats of woody stems set with 1-in. leaves that are green above, white and felted beneath. In late spring or early summer, 4–12-in. stalks carry clusters of tiny yellow flowers that age to rust.
