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.
Sow immediately at any time onto preferably a soil-based compost, covering with fine grit to approximately their own depth. Germination MAY be quicker if kept at 15 to 20 degrees C. but many seeds WILL NOT come up the year they are sown, needing winter chilling after sowing, and ONLY come up with natural spring germination.
