That was my biggest semp last year end of July at a diameter of about 5".
After having taken off the offspring it grew on and has now reached a diameter of 9". It's about to produce its second set of offspring. All 4 offsets produced (on short stolons fortunately) survived the winter and are now themselves about 2.5 to 3" in diameter.
My wife wants me to transplant the mother in an even bigger pot to make it reach its full potential, but if it continues to grow like this it will reach it before I find time for transplant...
