It is a plant that I got some years ago from John M. He gave it the clonal name. Carlisle is a town near where he lives. Not sure if John still has a piece of this one but I divided mine a couple years ago and solld the pieces at a club meeting. Kicking myself for dividing it now as I could have had a multi spike plant. Oh well, live and learn right?
Well done, Wendy! She's beautiful! This clone is exceptionally vigorous; so, she'll be multi growth again in no time. It'd be nice if you could keep it big for a while. A multi-spike Lady Isabel is quite a feast for the eyes!
