Here's a form of Musa balbisiana from sunshine-seeds.com. The picture on their website shows a large plant, but so far this is growing very compactly. I suppose that it could end up being 20+ feet tall though, who knows.
Leaf detail:
Pseudostem closeup, showing typical yellow coloration of Musa balbisiana (not the best pic...something's wrong with the color on my camera on some shots):
For a size comparison, here's a picture of (from left to right) M. balbisiana 'Neue Art', M itinerans 'India Form', and M. X sikkimensis 'Daj Giant'. The two on the left both have 5 leaves, and the M. X sikkimensis is starting to unfurl its fifth leaf. Notice how compact the Musa balbisiana 'Neue Art' is! By the way, what does 'Neue Art' mean? I assume that is German. Is it "New Kind"?
