Chrysanthemum Form:
Chrysanthemum (semi-double): Counting 6 layers of petals which gradually decrease in size towards the center. Stamens can be normal, or somewhat petaloid (where the stamens become petals). Pistils are normal.
Rose Form:
Rose (semi-double): Counting 6 layers of petals, which are usually larger than the chrysanthemum form. Petals are larger on the outside than on the inside. Stamens and pistils are somewhat or mostly petaloid.
Most of my tree peonies can be identified with these two forms. Though I find that the descriptions above rather confusing. They sound so similar to me. The two forms seem interchangeable.
I think this NOID which is maybe Shimano Fuji can be classified as the Rose Form
Another Rose Form is Kamata Fuji
Another Rose Form is High Noon
Does this Red NOID fit a Chrysanthemum Form?
Not sure if Manchurian Promise has a Chrysanthemum Form or Lotus Form?
Wu Jin Yao Hui - is this a Chrysanthemum or Rose Form?
