Oenothera gaura (Biennial beeblossom)
Brundage, Stephanie

Oenothera gaura

Oenothera gaura W.L. Wagner & Hoch

Biennial Beeblossom, Biennial Gaura

Onagraceae (Evening Primrose Family)

Synonym(s): Gaura biennis

USDA Symbol: OEGA

USDA Native Status: L48 (N), CAN (N)

Long-tubed white flowers, turning pink with age, bloom 2 or 3 at a time in clusters on long, wand-like spikes branching from the top portion of this 2-6 ft. biennial.

Species such as this one, formerly placed in the genus Gaura, are typically rather weedy plants, with leaves borne singly on the stems and frequently in a basal rosette. The flowers are in spikes or racemes, or are branching. They open in the evening. The 4 petals are on the upper side of the flower, giving it a slightly bilateral symmetry. There are normally 8 prominent stamens and 1 pistil; these are on the lower side. The stamens have reddish-brown anthers. The genus is easily recognized, but the species are sometimes difficult, due partly to a great deal of hybridization.
