Rudbeckia hirta is native to the eastern and midwestern United States. The genus Rudbeckia honors pioneering Swedish botanist Olof Rudbeck, who established the world-renowned Uppsala Botanic Garden that employed the “father of modern taxonomy” Carl Linnaeus as a resident professor. The species name hirta literally translates to “hairy,” referencing the tiny bristles covering the entire plant.
