According to "Hypericum Online", it is found from Maryland to southern Illinois, south to Florida and Louisiana,[4] though this may be in error, as many other sources list it as occurring only in Georgia and South Carolina.[1][2][3][5] Kew's Plants of the World Online notes that it may be extinct in South Carolina.[1]
Georgia St. John's wort was first formally described as Brathys erythraeae in 1836 by Édouard Spach. In 1840, Ernst Gottlieb von Steudel moved it to the genus Hypericum.[6][5]
