Wildflower

 

Synonyms:

  • Narrow-leaved Evening-primrose

Pollinator: Butterflies, skippers, bees - in particular, the sweat bee Lasioglossum oenotherae.

 

Comment:

Although classified as an evening-primrose, the flowers of O. fruticosa are wide open during the day.

Interestingly, the Visible veining on the petals carries over to both UV-dark veining and IR-dark veining.
