Like other members of the Asteraceae, the chrysanthemum produces a "flower" which is actually many florets grouped together into a single head. Each head is composed to a central group of short disk florets surrounded by rings of longer ray florets. All classes of chrysanthemums have both types of florets, but in some cases the disc florets are not visible. Mums are classified according to the type and arrangement of the florets: | ||||||||||||||||
