There's a bunch of em that'll take some serious cold!
Basjoo and Mekong giant are hardy here with no or little protection... Also musella lasicarpa makes it here with with mulch on top, as will veluntina and mannii
They won't fruit tho, not really.
The only way to really get fruit on a musa outside of zone 9 is to grow the plant to a hefty size in a big pot for the first year, then plant in ground for year 2... It just takes such a long season to even get fruit, much less ripe fruit!
