Close up of an American Basketflower (Centaurea americana) at Sims Bayou Urban Nature Center, Houston, TX, USA. Like other members of the family Asteraceae (including sunflowers, daisies, and dandilions), the basketflower is not a single flower, but an inflorescence (many small flowers together in one structure).
