Musa Basjoo gets to be a big plant, 10' - 12' or more. Obviously it would be limited when grown in a pot but it is still not suited for pot culture. For a Musa it is ridiculously hardy, do you have a spot outdoors to plant it? For a container I would suggest a Dwarf Lady Finger, Dwarf Cavendish, I think there is a Tiny Tim and there are several decorative ones with red and green variegation on the leaves that stay modest in size.
