Well, first off, the maroon one you didn't have a name for is an
Ensete Ventricosum 'Maurelii' which is also known as the Red Abyssinian banana. Ensetes are actually not real bananas, they're 'false' bananas, being part of the genus 'ensete' rather than the banana genus 'musa.' Hope that helps ya (and I'm sure you can find more information on the
wiki page about it).
As for the wilt, it looks like it's just stress from the heat during the day. The leaves on my bananas fold flat during the hot part of the day, then kinda pick back up at night. Nothing to worry about. Maybe someone else sees something I don't but that's my take on it, anyway.
