Donuel - if it is a musa (banana) and it fruits -the fruit should be edible - but may require cooking - and possibly may be considered "inedible" if it is one of the rare forms that contain seeds. As far as I know none of the bananas or plaintains are actually inedible - though some are not very tasty.

the flower buds of bananas can be steamed or boiled or roasted or baked as well. (Guess I should have just said "cooked")
