Due to the 58th Presidential Inauguration, the U.S. Botanic Garden will be closed January 18-21, 2017. We will reopen at 10 a.m. on January 22.
Known commonly as Winkler's gaillardia, these plants are found in only one county in eastern Texas. This endangered species is extremely well-adapted to the dry conditions of its native habitat, the sandhills of the east Texas pineywoods, and could prove to be a wonderful garden plant. Development and fire suppression have threatened the survival of this endemic and rare species. Currently there are efforts to protect remaining habitat and to study the effects of periodic controlled burning on threatened plant populations there.
