Description

Biennial Gaura is a native biennial or short-lived perennial wildflower found in wooded areas, streambanks, disturbed areas, open fields, and roadsides. In NC it is found primarily in the mountains and lesser so in the Piedmont.

This plant is adaptable to various well-drained dry to moist soils and prefers full sun. It is best used in naturalized areas and pollinator/native gardens. It can be slightly weedy. Flower stems sway beautifully in the breeze and bloom June through October. They are a great pollinator magnet.
