About

Oenothera gaura, formerly known as Gaura biennis, the biennial gaura or biennial beeblossom, is a North American flowering plant that can reach 6 ft (1.8 m) in height at maturity. Its upper half is made up of flowering stems, which are covered with soft, white hairs. It has light pink colored flowers, which turn a vibrant red/pink color in the late summer to early fall seasons (typically August to September). These colors make this plant attractive to butterflies and bees, and are in full bloom just before many fall plant species begin to bloom.

Research has been done in order to test the hybridization between different species of the section Oenothera sect. Gaura and to describe why many members of this group are so similar morphologically. According to Carr et al., readily crossbreeds with Gaura longiflora (now called Oenothera filiformis), and showed it is a direct derivative from G.
