Large aroids for shady porch?
I have a north-facing porch that gets relatively bright light but no sun whatsoever. I've grown caladiums successfully but are there any other big-leafed aroids that do well in containers and can take some shade? I need to avoid things like Philodendrons because I just don't have room to bring them inside in the winter. Can any of the elephant ears--Alocasia, Colocasia, Xanthosoma--tolerate shade? I know they mostly prefer full sun, but I'll settle for surviving if not thriving.
BTW which caladiums have the biggest leaves?
