Chrysanthemum Photos by Class
Today's Chrysanthemums are highly evolved flowering plants. A member of the Asteraceae Compositae family, the Chrysanthemum is related to dahlias, sunflowers, marigolds, zinnias, and cosmos.
The bloom, appearing as a single flower, is actually hundreds of flowers called florets. Two kinds of florets are present in a single bloom, disk florets and ray florets. For example, in the daisy-type chrysanthemum (class 7 below) each type of floret is easy to see – the outer parts are ray florets and the center or eye is composed of disk florets. The National Chrysanthemum Society classifies bloom forms into 13 classes as below.
Class 1 Irregular Incurve
These are the giant blooms of the chrysanthemum genus. The florets (petals) loosely incurve and make fully closed centers. The lower florets present an irregular appearance and may give a skirted effect. Class 1, Irregular Incurve, is the giant of the chrysanthemum family. Their form curves in, presenting a loose, irregular appearance. Many contain skirted rows of petals (florets). They are best disbudded.
