Illustration of Pale Evening Primrose (Oenothera pallida)

Pale Evening Primrose is a delicate, white-flowered evening primrose of sandy soils and desert margins in the western United States. Its white flowers open in the evening and emit a sweet fragrance to attract sphinx moths and other night-flying pollinators. The flowers turn pink with age. It is adapted to grow in loose, sandy soils where it can spread by rhizomes to form open colonies. In the Great Plains, it blooms along sandy river banks and dune areas, providing nectar for pollinators on warm summer evenings.

Habitat
Sandy soils, desert margins, river sandbars, and open dune areas of the central and western United States.
Diet
Fragrant white flowers pollinated by sphinx moths at night; seeds consumed by small rodents and birds.
