The dwarf Bananas we have which do well are Raja Puri (dessert banana), Dwarf Orinoco (cooking banana or eaten really ripe out of hand), Dwarf Red (delicious dessert banana, but ours take 18-24 months to fruit), dwarf Namwa (dessert banana). With all of these, if you buy a tissue culture plant, don't expect a guarantee it will be dwarf or even the correct plant. There have been mix ups with tissue cultures - whether mixing up germplasm or mutations during propagation. Ours are all around 6'. The dwarf red and dwarf Namwa seem the most notorious for growing tall after tissue culturing. Our original plant material was pups from friends. Raja Puri tissue cultured plants have been mislabeled in the past, but maybe the issue has been corrected.
