Ashy Sunflower
Helianthus mollis
Ashy sunflower is a native prairie perennial grown for its grayish, hairy foliage and bright yellow, brown-centered flower heads that bloom from midsummer into fall. It spreads by rhizome and by self-sown seed into loose colonies, so it suits open ground better than a tightly kept border. Goldfinches and other seed-eating birds feed on the ripened heads, and native bees draw special value from its blooms.
