Hi guys,
I am Italian too, but from the North.
Here Bananas are grown in many gardens since my memory can recall. There was an article on the city news paper a few months, saynig that a 30yrs old cultivar of Musa Paradisiaca had grown edible bananas... thanks also to the greenhouse effect, that turned our zone 7 into zone 8 or even higher.
Looking at your pics, I'd say your bananas are Musa Paradisiaca or Cavendish or even Dwarf Cavendish. These are the most common cultivars here in Italy, I'd say up until now, the only ones.
Possibly, considering that Sicily has a very mild climate, in the therms of North Africa, infact there you can grow Ficuses, Birds or Paradise, Cacti, outdoor without protection; I was saying consindering these important factors, I guess that the Common Sicilian Banana must have been imported from Asia or Africa many centuries ago, where it was an endemic specie, therefore it must be simply one of those Musa Sp. we all love. Matter of fact, bananas species among other exotic stuff, where imported massively during the Roman Empire.
Ciao,
G
