Bananas will pretty much always be dwarfed in a pot, except some of the ornamentals like ornata and velutina which can grow full size and flower fine in containers as small as 5gal. For the larger varities, whatever pot you put them in they will fill up quickly, you will also notice that at a certain point, a potted banana plant may continue to produce leaves but never really get any taller, at this point would be an ideal time to repot into a larger container. If it works for you though, you can plant them directly into a very large container. Potted bananas are trickier to get fruit from, dwarf varieties in large containers work best, the tall ones will grow into a nice plant but may never have the root capacity to properly sustain a fruit bunch (unless you have a really large container, which if you donʻt have to move around would be the best choice). On the flip side, bananas are also pretty good at staying in a small pot for a long time, they will stay small but they wonʻt die, so you can be the judge of how big you want your plants to be as they will quickly outgrow pretty much anything you put them in.
