Interesting, Sue
I would have no problem with modifying the current sculpt classifications to 4: 1) pleated 2) cristate 3) relief 4) other appendages
We will, in time, have other "appendages", I think.....raised areas on the petal surfaces that could fit there as well.....teeth, pimples, turkey feathers.....who knows what the future holds. I have had conversations with other hybridizers about taking seedlings that display random teeth in the middle of petals and crossing them together to stabilize that trait.
