Yellow Evening Primrose, Oenothera biennis
This bright and prolific biennial produces evening primrose oil, used for treatment of many skin and inflammation-related disorders. Oenothera biennis can reach 6 feet. It reseeds easily and can become weedy if left unchecked. Despite this, evening primrose blooms cheerfully long and late into the fall, providing important food for butterflies, moths, and bees. 50 seeds/$2.00, 1/2 oz./$10.00.
