'Also known as Sulfurflower, this plant is especially showy in the rocky, sagebrush flats. The sulfur-yellow blossoms are in an umbrella-like cluster at the top of a 10 to 12 inch flowering stalk, while the numerous leaves grow very near to the ground and accumulate bits of organic matter which eventually become part of the soil. The flowering period extends from mid-June to early August'. (1)
