Here's an updated pic of my Gros Michel:
I used to have two but I annihilated one (along with an unsuspecting Glui Khai and almost my Zan Moreno, which has managed to pull through).
Bananas are tough, but they can be killed if you're persistent enough. I've found that if I receive a tc plant in the mail after it has traveled a thousand miles in a box, then do my best to shock it by scrubbing all the dirt off its roots and immediately planting it underwater in a solar furnace without allowing it to acclimate, it'll still flourish in spite of it all. But if I then ratchet things up even further by digging it up and moving it a week or two later, and then doing so again after another week or two, then there's about a 50-50 shot it'll call it quits.
The things are so tough that I'd almost gotten to the point of treating them as if they were indestructible, even as young tc plants.
