Did you know there are 13 classes of chrysanthemum flower? This is Class 1, the irregular incurve. The florets form a seductive inward curve, closing the center. Below they hang more loosely, forming a skirt. This cultivar is & #39;Bola de Oro.& #39;
Class 2: the reflex. Ray florets gracefully lie downwards, voluminously overlapping one another. The top sometimes appears flat, and the disc florets may even be exposed. This Class 2 cultivar is & #39;Joyce Fountain.& #39;
Class 3 is wonderful: the regular incurve. The florets extend outward and slightly up along the edges forming a soft ethereal sphere with no skirt. This perfect marshmallow is & #39;Gillette.& #39;
Class 4: decorative. A flatter inflorescence with florets curving up and inward at the top (incurve) and increasingly downward as you move towards the bottom (reflex). Here are & #39;Annie Girl& #39; and & #39;Honeyglow& #39; decorative mums.
Intermediate incurve blooms fall in Class 5. These incurve blooms are more relaxed and a bit smaller than Classes 1 and 3. The ray florets are more weakly incurved, but they still cover the center disc florets. Here is Class 5 & #39;Norton Vic.& #39;
Class 6 are the pompons. Small puffy cushions or globes with very regular florets. Here are our still maturing & #39;Kelvin Tattoo& #39; and & #39;Moonbeam& #39; at Longwood Gardens (their photo).
Class 7 are the daisy-like blooms, the single and semi-double mums. The center disk florets are clear and visible, surrounded by one or more rows of ray florets (the "petals"). Here is a simple but charming Class 7 light pink cultivar.
The anemones of Class 8 are super fun! Simple outer ray florets, but the center is a raised puffy cushions. Here are & #39;First Light& #39; and & #39;One Scoop,& #39; which is a really cute name for the inner cushion tbh.
Spoons! That& #39;s what Class 9 is all about. The center disk is still visible, but the outer ray florets are tubular to start and then open at the ends, looking like a bunch of spoons sticking out. This disbud & #39;Kimie& #39; and spray & #39;Donna& #39; show off their yellow spoons.
Class 10: quill. The centers are hidden. The outer ray florets are fully tubular with an open tip like a straw without broad unfolding like on the Class 9 spoon blooms. Here & #39;Seaton& #39;s Coffee& #39; is showing off its lovely bronze quills.

This gives them a wild spidery appearance. Here is the beautiful spider & #39;Mystic.& #39;
