Oenothera biennis
The common evening primrose is a native Oregon wildflower which can be found throughout most of North America. It can produce single or multiple stems with leaves growing in an alternating pattern along its length. Mature specimens will typically reach a height of up to 60 inches (152 cm). The plant will produce large yellow flowers consisting for four overlapping petals. As the name suggests, the flowers open at dusk and close at dawn.
The plant’s leaves have been traditionally used as a food source for local Native Americans. More recently, oil derived from the primrose seeds have been used as a homeopathic remedy for relieving pain or treating bruises and other injuries to the skin. Currently, there is some controversy over whether these homeopathic uses are truly beneficial.
Common evening primrose can be alternately known as evening star or sun drop.
Distribution
It can be found in nearly every state in the United States. It can thrive under a variety of conditions and tolerates both acidic soils and direct sunlight. The plant can be found naturally-occurring in dunes, meadows and woodlands. Because it is fast-growing and tenacious, it may take over yards quickly and be considered a nuisance species.
Conservation Status
Common.
