It's most likely a Musa sikkimensis X Musa balbisiana hybrid, based on leaf characteristics, so it wouldn't be a species.
I'll bet it is as hardy as Musa sikkimensis, and maybe less so in some cases where a particular seedling got less genes from the sikkimensis side of the family. It hasn't been grown for very long, but I sprouted one last december, and by the time autum rolled around it was a good seven feet tall and big enough to test out doors, but I sold it instead before I moved north.
