See the tiny disc (disk) florets at the center of a sunflower head open in waves. This sunflower time-lapse video by Neil Bromhall captures each burst of blooms.
There are around 70 species in the genus Helianthus. Tightly packed into a spiral at the head’s center, disc florets are small flowers that mature into sunflower seeds, the plant’s fruit. The outer flowers are ray florets.
Young sunflower heads are famous for heliotropism or tilting toward the sun, but generally face eastward as they reach the stage seen in this video.
