Oenothera albicaulis is a New World plant in the evening primrose family. It is known by the common names prairie evening-primrose, white-stem evening-primrose, whitish evening primrose, or whitest evening primrose.
Oenothera albicaulis is native to North America, in the United States (Arizona; Colorado; Montana; New Mexico; Oklahoma; South Dakota; Texas; and Utah), and in Mexico (in Chihuahua state).
The Zuni people rub the chewed blossoms on the bodies of young girls so that they can dance well and ensure rain.
