Onagraceae (Evening-Primrose Family)

Synonym(s):

USDA Symbol: OEEL

USDA Native Status: L48 (N)

A tall, erect, usually unbranched stem with large yellow flowers in a raceme.

Common Evening-primrose (O. biennis), found throughout most of the United States, has similar erect stems, but its petals are less than 1 (2.5 cm) long. Both are closely related to the Garden Evening-primrose (O. erythrosepala), scattered in the wild from western Washington to California, which is a taller plant, with redder sepals, paler petals about 1 1/2 (3.8 cm) long, and crinkled leaves.
