Hello,
As Susan mentioned above, banana plants can be stored over the winter. This technique is probably not well known but makes it possible to grow bananas up north and get fruit. Basic selections factors for a plant might include:
1) a smaller sized banana plant
2) one that tolerates some cooler conditions
3) one that grows quickly and has a quicker production cycle (not essential but might be useful
Basically, the plant is dug up in the fall. All of the soil is removed and the leaves are trimmed off. Store it in a dark place. The temperature range must be above freezing but keep it lower than 52 deg F or it might try to grow. Just keep it dry and in the spring, replant it outside once temps are above freezing.
The technique is illustrated on this German site
