At 10" diameter 1 rosette would cover about 1/4 of my plates - enough space for two smaller cultivars...I they really get that tall they might have to go to my parent's garden with plenty of space to spread...
Enclosed two fotos of the bigger rosette at about 5 cm (app. 2") diameter, one from december 2015 and one just taken two weeks ago...
And here is an older one from last september (cut out from one of my "identification fotos") showing all three rosettes.
