And now I'll tell you that we have them in several different locations on our campus (Cal Poly Pomona) in full sun and heavy shade, rainwater only and watered 3 times a week and they all grow nicely. The ones in sun are denser and the ones in shade are taller and have bigger leaves. Practically indestructible.
I did have one(Strelitzia nicolai) in an enclosed atrium with a clear skylight that bloomed when it had about 4' of trunk. Sucked up water like a dehydrated elephant.
