Post-Extinction Plant Update

Cool. I have 2 banana plants in my discus tank now, and I had them in other tanks previously. They will shoot up a lily pad thing to the surface, and if there is any current, the stem can grow really long, like several feet. I've cut them off, and in a few weeks they'll shoot up another lol.
 
Did you know, if you cut it off and leave about 4 inches of the stem on the pad, and leave it floating, that stem will grow another banana plant in about a week or more. The new plant usually doesn't have any tubers, though.
 
just the lily pads?
or any of the leaves?
