Helianthus cinereus is a native North American sunflower, a natural hybrid found in the central United States, with silvery-grey foliage. It is a wild prairie species rather than a common garden plant, and is grown in full sun with well-drained soil.
Helianthus × cinereus is a species of sunflower native to the United States, in Missouri, Kentucky, Indiana, and Ohio. H. cinereus was proposed as a new species by Torrey and Gray in 1842. It is a natural hybrid with similar features to artificial hybrids between Helianthus mollis and Helianthus occidentalis.
