Using shade trees outside,as opposed to awnings, would shade the whole building & could provide tasty goodness if they were fruit trees
Banana trees though? Not much positive climbing wise for the boas and can't they only fruit once?
*envisions boas slithering through smushed nanas*
Why not citrus? Good food, different variety, easier clean up, natural deodorizer, good climbing, easy to train (bonsai techniques), flowering.
Egyptians, Mayans & Aztecs were awesome, it's a shame we don't have access to their history.
