Also forgot to mention, wind shreds the leaves, I like the look either way, shredded or not, but if you can provide some shelter from the wind it'll help keep the leaves intact.
Be sure to give it plenty of room!
Even here in Kentucky, I have bananas go from 6" tall in a 6" pot, up to 10-15' is one season, they don't all get so big, but once established, almost all of them grow really REALLY fast!
