sunflower head

Yellow ray cluster

The sunflower head is the large, circular flowering structure of the sunflower plant, consisting of hundreds of tiny individual florets arranged in a spiral pattern.

What appears to be a single flower is actually a composite—the outer yellow petals are ray florets, while the dense center contains disc florets that mature into seeds.

Dried sunflower heads are harvested for their edible seeds or left standing for birds to forage.
