Eriogonum umbellatum is a species of wild buckwheat known by the common name sulphurflower buckwheat, or simply sulphur flower.
It is native to western North America from California to Colorado to central Canada, where it is abundant and found in many habitats.
This is an extremely variable plant and hard to identify because individuals can look very different from one another. Also, there are a great many varieties. It may be a perennial herb forming a small clump with flowers to 10 centimeters tall, or a sprawling shrub approaching two meters high and wide. The leaves are usually woolly and low on the plant, and the flowers come in many colors from white to bright yellow to purple.
Native American groups utilized parts of this plant for a number of medicinal uses.
