The Confederate daisy is well-known to many southerners, and photographs of it are found in the popular wild flower books by Duncan and Foote (1975) and Rickett (1967), where it is listed as Viguiera porteri (A. Gray) S. F. Blake. This fall-blooming annual herb may reach to about 1 meter in height (or taller in gardens) and is “wholly confined” (McVaugh 1943) to “thin soil about granite” flat-rocks and granitic domes (Cronquist 1980), interesting habitat islands that dot the Piedmont Province of the southeastern United States. Factors responsible for its endemism to granite flat-rocks were discussed by Mellinger (1972). The Confederate daisy may be locally common to dominant on granitic flat-rocks, most of which “are not prominently elevated above the surrounding piedmont, Stone Mountain being atypical” (Wurdack and Wurdack 1978).
