Yours is very green. But you reminded me of this one potted hosta (this is one pot) I purchased last year at a local garden center. It seems to have BME and a friend. Or it was originally the friend and it reverted to BME. I separated these and planted them apart. They are still in pip phase but I will update when they leaf out.

This seems to happen frequently with the mice collection. I had Mighty Mouse give me three all gold eyes. I separated them out - MM is know to produce the sport Midas Mouse. Unfortunately Midas Mouse didn't survive. Looks good in the one pic I have but all three eyes died. :(
