Disc florets are the small, tubular flowers found in the center of a sunflower head, which is known as a capitulum. They are typically yellow or brown and are responsible for reproduction, as they contain both male and female reproductive structures. In sunflowers, these florets are surrounded by larger ray florets that are more visually striking and often mistaken as individual flowers. Together, they contribute to the sunflower's overall appearance and reproductive success.
