I would love to have one. I had one last year and lost it by the end of summer. It was doing OK for a while, but didn't make it to the end of the summer. I realize now that I did not have it in the best spot for the "fussy" ones.
Your 'Pink Pearl' looks white-ish and is very nice. Did I mention that some of the calcareums are known to get large? None of mine have ever done that, but I just started collecting them last year and haven't seen full size on some of them yet. I had a rescue calcareum two years ago that first attracted me because it was almost white. Of course, it was fussy and dried out too much over wintering.
Here's a picture of S. calcareum 'Sir Wm. Lawrence'. I think this one can get large and is sort of majestic in a calcareum way.
