Sol,
The pure wulfeniis are really not good plants. Pretty yes but horrid for growth, one increase/ year and on "too sturdy" stolons, at least for my taste. Mine eventually bloomed itself out.
The only problem is it does make lovely formed rosettes and we'd love to have that form in all sorts of colors and sizes. It is in the pedigree of things and it might be possible to select for things that carry lots of wulfenii genes but not the horrible growth. I was pleased to get some things from 'Silver Song' that are more wulfenii-like in form.
Kind of late for transplanting as they won't make new roots until spring from what I've seen. I'd hold off until March.
Kevin
