About

Oenothera grandis, variously showy ragged evening-primrose, grand evening primrose, or large-flowered cut-leaved evening primrose, is an annual plant that is native to the southern Great Plains and parts of Mexico.

Where it grows

Showy ragged evening-primrose is native from Nebraska, Colorado, and Missouri southwards in the United States and to northeastern and southwestern Mexico. The many reports in states east of the Mississippi are likely recent introductions. In Mexico it is known from just three scattered states, Durango and Tamaulipas in the north and Michoacán in the south.
