This strain of the Cavendish banana will actually produce fruit at a manageable height of just 3’ or less. The bananas will appear often after one year. Container grown bananas can be wintered over in a sunroom, an above freezing garage or cellar. Banana plants grown in a garden can be dug and lifted out of the ground before winter and stored in an above freezing area. The plant will have yellow leaves but the trunk and some of the roots will be alive waiting for the next growing season. This is one way to grow bananas in the north. This method also helps to contain their size so they are manageable. Often Dwarf Banana plants are found growing in parts of Asia for mass cultivation and they are sometimes grown as tall specimen plants in gardens at the back of borders to add a touch of the tropics. These "Dwarfs" can still easily reach 6ft / 2m, so with this in mind a young new plant will live happily on a window ledge for a few years at most but that's it, afterwards the space will have run out and you will need somewhere bigger. They grow quickly when it's warm, rewarding you with one new leaf every week or so, they look truly stunning and unique all the time, adding a tropical interest to any area. If allowed to reach its statuesque proportions, it will dominate in a graceful balanced way that very few houseplants can ever match.
