Does it actually produce fruit?
The Basjoo species of banana is the most commonly found, one can even grow it out in our climate without protection, as it is simply a hardy ornamental banana, however I'd love to think there are other edible banana owners out there.
Sadly though it is becoming more possible due to the creation of "super dwarf" bananas. Normally a banana tree should reach the height of 12-17 feet high. Super dwarfs reach 2-4 feet.
