The Rocky Mountain states and all states to the west
Up to 3 inches - forms spreading mats
Tundra, gravelly slopes, rocky areas, near melting snow; from sea level to 13,000 feet
Ternately divided into toothed, wedge-shaped leaflets, up to 1 inch long
Sibbaldia procumbens forms low mats, and is inconspicuous even when in bloom; the flowers are small, formed of five green, linear bractlets, five wider, veined, triangular, green sepals and five tiny yellow petals, less than 0.05 inches long. The sepals and bractlets become reddish with age; and persist for some time after the petals have withered. The petals are positioned above the bractlets, with the sepals in between, displaced by 72 degrees. At the center are five yellow stamens with relatively large anthers, and up to 15 carpels.
Stems and leaves have a sparse covering of appressed hairs. The veined, greyish-green leaves grow on stalks up to 3 inches long, and are compound, with three leaflets; these are narrow at the base, wider and flattish at the top, which is partly divided into 3 small lobes, or teeth.
