The generic name Oenothera is derived from Greek words oinos meaning "wine" and thera, which means "to hunt". The common Oenothera is a biennial plant that gives rise to a bunch of yellow flowers in a cross-like form. These flowers bloom in the evening and stay wide open during the next day; hence, the common name - Evening star. This plant is usually found in the moderate climates of North America. It can also be found in sandy soils on roadways and along railway embankments in Germany.

Formerly, during the Fall, the roots collected were used as vegetables and the seeds which have an aromatic taste, were used as a substitute for coffee during wartime. The other common names of Oenothera are fever plant, sun drop, suncups, night willow herb, King's cureall, tree primrose, scabish and scurvish.
