where it is abundant and found in many habitats, including the sagebrush steppe and alpine areas.[1] It is an extremely variable plant and hard to identify because individuals can look very different from one another. Also, there are many varieties. It may be a perennial herb blooming by summer[1] with stems 10 centimeters tall[citation needed] and two to six clusters of flowers, with a whorl of leaves below the stems,[1] or a sprawling shrub approaching two meters high and wide.[citation needed] 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.
It is a popular larval host, feeding the bramble hairstreak, desert green hairstreak, lupine blue, Mormon metalmark, Rocky Mountain dotted blue, Sheridan's hairstreak, Sonoran metalmark, and western green hairstreak.[2] Additionally, goats and domestic sheep feed on the plant.[3]
