Helianthus porteri

About

Helianthus porteri is a species of sunflower known by the common names Porter's sunflower, Stone Mountain daisy and Confederate daisy. The term "daisy" is imprecise because the species is a sunflower (Helianthus) rather than a daisy. Likewise, although the plant grows on Stone Mountain, GA, its range extends well beyond. The connection to the Confederacy is through Stone Mountain which contains a confederate monument, although the connection is tenuous as the species was named before the Civil War in 1849 by Harvard botanist Asa Gray in honor of Thomas Conrad Porter, a Pennsylvanian minister and botanist who collected the plant in Georgia. Gray initially named the plant Rudbeckia porteri, later changed to Helianthus in 1998 by John F. Pruski.
