Sulfur Flower (Eriogonum umbellatum)

Natural History

Sulfur Flower is a member of the Buckwheat Family. It forms a circular cluster to 4 feet across and grows to 12 inches in height. Leaves are oval with fuzzy undersides that grow to 1.5 inches in length. It grows in dry areas from sagebrush deserts to foothills and alpine ridges.

Sulfur Flower is highly variable, making it difficult to distinguish between other similar species.

Sulfur Flower blooms between June - August and produces a spherical cluster flowerhead to 2 inches in width composed of smaller tubular flowers, each to 0.5 inches in length. The flowers fade to orange or red as they age.
