Ball – Blooms are ball shaped with uniform florets, involute for most of their length, and fully involute for more than half the length: the ray florets reflex toward the stem. Ray floret tips in cross-section should be circular and exhibit little distortion, completely filling the floral head and are either round or blunt without notch or point.

Miniature Ball- Except for size, miniature ball and ball dahlias possess the same form features.

Pompon- The ray florets are involute for whole of their length and fully involute for half their length. Except for size they are similar to the ball description.
