Rayless Sunflower, Helianthus radula, is a sunflower that produces a tight cluster of purple to brown, tighly packed disk flowers atop a long stalk.  This sunflower lacks the showy, outer ray flowers of the inflorescence typical of other members of the Asteraceae, like daisies.  It has large, rounded, hairy basal leaves growing close to the ground.  The native range of this species is the southern coastal plain from South Carolina to Louisiana and Florida.  It thrives in wet, sunny locations and is a great wildflower to use in native plantings and pollinator gardens.
