Anyone got the resources to find out?
I just figure if the temps are going below freezing for more than a morning cold snap, do something to protect it from 32f or less or else.

For myself temps have to be freezing for a couple of days for complete plant kill and a nice frost with 28F is a sure bet all all is lost to ground level.
Here is a fun experiment that any of us can do and the outcome will be the same.
This just demonstrates what a banana plant cell does when it freeze, remember banana plants contain lot of water.
You may even wrap the experiment in your warmest insulation hat,coat, glove.....the outcome will be the same.
Take a can of soda ,beer, monster and wrap it up real good in the best insulation and put in your freezer for a day or so.
For even more fun forgo the freezer and put the can on the dashboard of your automobile outside in freezing temps.
These will be real life temps that a plant will encounter in zones 4-7.
Remember cold freezes from the outside in.
Now for a moment lets envision that the can is an internal basjoo cell.
Will it explode?
What happens to things when they explode?
How many hours does it take to explode?
These links might be helpful and you might gets some ideas for an alternate way to grow these plants.
