Yes, I do!
The one outside got centre-rot. I cut it at the base a couple of weeks ago, and I am hoping it will come back with some pups. It would probably do better if kept dryer, but both my other sikkimensis and musa basjoo look as if they are growing and didn't loose their stems.
The conclusion is that more testing is needed, before we can say if it's as hardy as sikkimensis/basjoo, remember, this was only one plant tested outside in very wet/cold conditions. And the outside of the stems were green, only the inside got rot.
