Each Chrysanthemum flower head is actually a cluster of many flowers, composed of a central group of short disk flowers surrounded by rings of longer ray flowers. Chrysanthemums are classified into nine categories according to the type and arrangement of disk and ray flowers - Incurved, Reflexed, Intermediate, Late Flowering Anemones, Singles, Pompons, Sprays, Spiders, Spoons, Quills, Charms and Cascades. For example, the reflexed Chrysanthemum consists of ray flowers that curve downward into an umbrella shape; the quill has tubular ray flowers that radiate from the center of the head.
