Tufted Evening Primrose

Oenothera caespitosa

Plant Details:

Plant Type: Perennial

Plant Family: Onagraceae

Plant Description: The large, fragrant white flowers of this native primrose open at sunset, blooming from late spring through early fall. Their four heart-shaped petals start out white and turn pink with age. Rosettes of toothed, lance-shaped leaves are silvery and neatly mound-shaped. This xeric plant is tolerant of poor, well-drained soils, making it a great choice for rock gardens. Native to the western United States.

Maintenance:

Maintenance Type: Perennial - Herbaceous

Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
