Oenothera Odorata

Vast, three inch, fragrant lemon-yellow saucers open actually in the daytime on this adorable back-of-the-border plant, which is unusual in that the flowers open during the day time when they can be best admired. Evening primrose oil, derived from the seeds, is a well-known source of gamma linoleic acid (GLA), said to be a good dietary supplement for women in particular. The small drop of this nutrient in every seed serves as a readily available energy boost for the plant, allowing it to germinate and grow faster than its competitors.
