Description Evening primrose (Oenothera biennis) is a native biennial wildflower that sports edible shoots, leaves, roots, seeds and flowers. Highly aromatic (vanilla notes) from the attractive yellow flowers which open in the evening or similar conditions (hence its name). A great addition to the orchard as it both improves soil conditions, creates natural habitat and encourages the residence of pollinators and beneficial insects. Plants can grow anywhere from 2 to 6 feet tall, responding to early trimming to manage.
