Here's where we got to. I'll throw up some varietal photos and further thoughts once I get home
I grow 3 types of frost hardy bananas and am putting together a grove. I will try and pull a post together in due course but essentially the truly frost hardy banana species do not produce edible fruit - I'm talking here of Musa basjoo and Musa sikkimensis. They do however produce lovely banana leaves that have various culinary uses and they do look really cool.
There are also a few purported hybrids between edible banana varieties and these hardy types: Musa "Helen's Hybrid" is probably the best known - these will fruit in the right conditions but will not give you something that looks (or tastes) like a shop bought 'nana but it will be edible. New forms in this category seem to turn up pretty regularly.
Lastly there are the edible varieties grown in marginal regions (Sikkim or Dharjeeling are good names to see) or hybrids therewith which are probably your best bet - these will probably need overwintering somewhere frost free but might give you a shout on a warm summer having done so.
There is some fantastic info round this on musa.org
This is the aforementioned Musa basjoo at RHS Rosemoor (because mine aren't yet that big). These will see snow most winters I would guess and some quite hard frosts.
