Evening Primrose

Oenothera biennis, or Common Evening Primrose, is a biennial wildflower native to North America with sweet-smelling yellow flowers that bloom at night.

Evening Primrose's many blossoms open every night from late spring to early fall, making it far less elusive than the aforementioned Queen of the Night. (This is usually from May through July.)

Evening Primrose is a biennial, which means that it blooms every two years. It forms its stem and leaves in the first year, flowers, and dies in the second. The yellow, four-petaled blossoms have a lemon aroma and can expand to be up to two inches across.

Not only is Evening Primrose visually appealing and fragrant, but parts of the plant are edible, and it is the source of Evening Primrose oil, which is known to have numerous medical applications.
