About
Oenothera elata is a species of Oenothera belonging to the family Onagraceae, known by the common name Hooker's evening primrose or tall evening primrose. Subspecies include hookeri, hirsutissima, longisima, jamesii, villosa and elata. 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. The plants are found along roadsides, in moist meadows, or in woodland, from sea level up to 9,000 ft (2,700 m) in elevation.
Uses
The Zuni people apply a poultice of the powdered flower of the hookeri subspecies and saliva at night to swellings.
