I think most of them are from Guatemala or Honduras and they use them to wrap their tamales in.
They also will use corn husks, unfortunately my corn failed this year, so I has none to share.
I figure If I could grow the bananas for leaves, I could trade, share and sell them and maybe the pups as well.
The fruit of truly hardy bananas is said to be inedible, though if I ever get any, I will certainly see what I can do with them before I give them to the chickens.
