Remarks

Gorgeous! Luscious goblet shaped lemon yellow flowers on this native wildflower that also develops elongated seed capsules. The lighter, silvery sheen of the leaves distinguishes the O. macrocarpa var. incana subspecies, and is also an evening to morning bloomer.

Flea beetles have nipped at the O. macrocarpa species, but not to the extent of the O. caespitosa. O. speciosa, Showy Primrose, is another evening primrose, one with pale pink flowers, that will grow well in our area, however, it is invasive. Plant it in a location you’ll be happy with its spread.

Use in Garden

Sunny xeristrip, low water-use bed, native plant garden, rock garden.

Maintenance

Remove spent stems in late fall or late winter. Broadcast seeds from seed pods -- there will be many, or allow wildlife to feed on them.
