There are some forms of M. itinerans that are reported to be exceptionally cold-hardy. Whether or not the one Agri-starts and others describe and sell as M. itinerans 'Yunnan' is actually a variety of itinerans or not, it is a cold-hardy banana in zone 7. I still have a hard time with this banana's true identity though. It just doesn't fit the botanical description of M. itinerans at all.

It's all about provenance! There are varieties found at very high elevations, even some areas that receive annual snowfall and frost. Then there are others that are lowland varieties that may or may not show much cold-resistance. Wish someone would climb that mountain and get me some seeds!
