Hi Twit
'Fuzzy Wuzzy' and 'Whirl I Gig' were introduced because of their unnormal forms; the normal rosettes of them are undesired but often;
I know 'Mauna Kea' for producing crested rosettes - Erwin Geiger (german breeder) unfortunately named them 'Bizarre Rose'; but the most of the offsets turned back to normal:
'Venus' is also a cristat-producer like 'Bedivere' and a lot of semps-fans think it might be from the same seed....anyway from the same breeder;
then there is 'Rex' from David T. Ford; every year there are some crested offsets - but none of it has ever increased crested longer then two years;
other crested offsets are very rarely, not stable and often a reaction of stressed mother-rosettes; mostly combined with double-, triple and multiple-rosettes; they often seemed to be crested when young;
