Ray florets are the vivid, strap-like structures forming a sunflower's outer fringe. While appearing as petals, each is actually an individual, sterile flower. They feature a ligule—a long, tongue-shaped extension typically colored in brilliant yellow, orange, or deep red. Structurally, these florets are zygomorphic, meaning they are bilaterally symmetrical rather than circular. Their biological role is to serve as a visual billboard. Because they lack reproductive organs, they do not produce seeds. Instead, they act as high-contrast targets, attracting pollinators and guiding them toward the fertile disk florets at the center.
