Has anyone tested the ploidy for this rose? I have wondered if it is a tetraploid mutation.

David Zlesak reported it as being triploid in 'Pollen diameter and guard cell length as predictors of ploidy in diverse rose cultivars, species, and breeding lines'

Thanks. Interesting. Makes me wonder what exactly mutated for the new phenotype to spring up. Usually sports are less novel, like strictly a change in color for one genetic reason or another.

Two roses I have had no luck with are Cherry Mediland and Royal bonica. I live in central florida and I suppose the nematodes ate their roots. Not into pot culture so unless I find these varieties on Fortuniana rootstock I suppose I'l just have to suffer. Any ideas on this matter as to how I could raise them here???
