  • Photo of Oenothera gaura (Oenothera gauras)

Phonetic Spelling:ee-no-THEE-ruh GAH-ra

Genus:Oenothera

Species:gaura

Family:Onagraceae

The biennial Gaura is a wildflower native to the region, typically found in wooded areas, along streambanks, in disturbed sites, open fields, and on roadsides. In North Carolina, it predominantly grows in the mountainous regions, with fewer occurrences in the Piedmont.

This plant thrives in a range of well-drained soils, from dry to moist, and favors full sunlight. It is ideally suited for naturalized settings and gardens designed to attract pollinators and native species. While it can exhibit some weedy characteristics, its flower stems gracefully sway in the wind, producing blooms from June to October, making it an excellent choice for attracting pollinators.
