Jeffreyp, in Brazil I've seen one banana plant produce 4 bunches at the same time. I saw a picture edited at a Brazilian farmers magazine called Globo Rural where the farmer cut down the plant few inches above the ground and it produced a big bunch without any leaves at all.
That's why I believe there is something enigmatic, mystic, about the banana plants.
