Scott,
It is rather difficult to identify/differentiate one Banana variety from another. Except for some dwarf varieties that grow from 5' to 15', most are 15' to 25'.
They like uniformly warm climate like California and Florida, because it takes 12 to 18 months of frost free conditions to produce
flower stalk, then the fruits takes 4 to 8 months to mature...all depending on temperature. They do not require polliation.
Bananas require regular deep watering, especially during warm weather. Because they grow fast, they are heavy feeders. When fertilizing make sure it (fertilizer) does not come in contact with the trunk.
I have several Banana
trees of unknown variety[4 mature and 5 babies (shoots)]. They are planted outdoor and are about 25 feet. The mature ones are about 16 months old...but so far has no sign of
flower stalk.
