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]

The Zuni people apply a poultice of the powdered flower of the hookeri subspecies and saliva at night to swellings.[4]
