PlantsFlowering PlantsCompound Flowers — Family Asteraceae
A compound flower is made up of many smaller flowers called florets. Typically these are of two types: disk florets in the center, surrounded by ray florets. The head might not have both types of florets, and the asterids can be grouped into those with both rays and disks, rays only, or disks only. The asterids have parts in 5s, but this can be deceiving since ray florets may appear to be many petals until the plant has been identified as a compound flower.
