• Oenothera biennis - Evening-primrose


    "An upright biennial in the Onagraceae family.  It commonly grows in fields, prairies, glades, thickets, waste ground, disturbed sites, and along roadsides and railroad right-of-ways. This plant naturalizes easily and works well planted along boarders or makes an excellent addition to a wildflower, cottage, or herb garden. It is highly drought tolerant. Flowers open at dusk and close again in the morning when hit by sun, hence the common name of evening primrose.  Fruits are capsules (narrow seed pods to 1 1/2” long) which split open when ripe to release numerous seeds (to 100 seeds per capsule). Plants die after setting seed, but will naturalize in the landscape." (North Carolina Extension)
