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 'Bola de Oro.'
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 'Joyce Fountain.'
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 'Gillette.'
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 'Annie Girl' and 'Honeyglow' 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 'Norton Vic.'
Class 6 are the pompons. Small puffy cushions or globes with very regular florets. Here are our still maturing 'Kelvin Tattoo' and 'Moonbeam' 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 'First Light' and 'One Scoop,' which is a really cute name for the inner cushion tbh.
Spoons! That'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 'Kimie' and spray 'Donna' 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 'Seaton's Coffee' is showing off its lovely bronze quills.
I saved Class 11 for Halloween - spider 
These mums have quite long tubular florets that usually curl at the ends instead of being straight like Class 10. This gives them a wild spidery appearance. Here is the beautiful spider 'Mystic.'
