Subspecies include hookeri, hirsutissima, longisima, jamesii, villosa and elata.[1] It is native to much of western and central North America. The plants are quite tall, especially the hookeri subspecies, native to California, which can reach about 1.8 meters (6 feet) height.[2] The plants are found along roadsides, in moist meadows, or woodland, from sea level up to {{convert|9000|ft|abbr=on}} in elevation.[3] DescriptionThe stout, usually reddish stem has many long, narrow leaves, above a basal rosette. At its top is a large, open cluster of 2- to 4-inch wide yellow flowers with 4 large petals and protruding yellow stamens and 4-branched pistil, often covered in sticky pollen. The fragrant flowers open at dusk and wilt the next morning, turning orange or red.[3] UsesThe Zuni people apply a poultice of the powdered flower of the hookeri subspecies and saliva at night to swellings.[4] GalleryReferences1. ^{{GRIN | accessdate = 19 January 2018}} 2. ^"Botanica.
