In Italian it's "melagrana", at least that's what my grandma used to call it so I don't know if it's a dialect or something...
it's not a dialect, it's correct Italian. It is also used "melograno".
Look at this Botticelli's painting, named after the melograno (Madonna of melograno)
I don't want realism. I want magic! Yes, yes, magic. I try to give that to people. I do misrepresent things. I don't tell the truth. I tell what ought to be truth (Blanche/A streetcar named desire)
