Here is what it looks like today, two months later. It is pretty fast-growing, unfurling a week every 5-7 days, and it is getting some nice size to it. I sure do hope this one is cold-hardy, because it is my favorite banana (er, right now, that is...ask me next week). I think it's holding onto eleven or twelve green leaves at this point too.
And look what I found yesterday. A pup! And it is pretty close to the mother pseudostem. It seems there are "traditional" type pups, and then there are the long rhizomes that send pups out a couple of meters away. This one, obviously, appears to have come off the corm.
