Class 1

Irregular Incurve

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 2
Reflex 

The florets in this class curve downward and overlap, similar to bird plumage. The tops of these blooms are full but somewhat flattened. 

Class 2

Reflex 

Class 3
Regular Incurve

A true globular bloom equal in breadth and depth. The florets smoothly incurve and form a regular ball. 

Class 3

Regular Incurve

Class 4

Decorative

Class 4
Decorative

As in the above classes, the center disk should not be visible. The upper florets tend to incurve, but the lower petals generally reflex. 

Class 5

Intermediate Incurve

Class 5
Intermediate Incurve

This bloom class is smaller than the irregular incurve with shorter florets, only partially incurving with full centers, but giving a more open appearance.

Class 6

Pompon

Class 6
Pompon

A small globular bloom, somewhat flat when young but fully rounded when mature, Size ranges from small button types to large disbudded blooms almost 4" in diameter.  The florets incurve or reflex in a regular manner and fully conceal the center.
