Organ Mountain evening primrose is a rare perennial wildflower native to a few valleys in New Mexico's Organ Mountains, known to science but seldom grown. Its main practical point for gardeners is that it is a rare, wild species and should not be collected from the wild.

About

Oenothera organensis, the Organ Mountains evening-primrose, is a species of flowering plant in the family Onagraceae, native to a few valleys in the Organ Mountains of New Mexico. With only a few thousand individuals, it is nevertheless well-studied due to its complete self-incompatibility, which would seem to be maladaptive in such a rare species.
