It is native to the western United States, including the Great Basin, where it grows in habitat such as sagebrush and forests. It is a perennial herb growing from a woody caudex and taproot, sending up an erect, mostly unbranched stem which may be 70 centimeters tall. The lance-shaped leaves are up to 8 centimeters long around the caudex, and shorter farther up the stem. Flowers occur in a terminal cyme and sometimes in leaf axils. Each flower is encapsulated in a hairy, glandular calyx of fused sepals. The five petals are creamy white or pink-tinged in color and each has four to six long, fringelike lobes at the tip.
