Tall leafy tropical look for full shade foundatn?
I was planning to put in a row of tall "Elephant Ears" along a big blank north wall which gets no sun except very late afternoon in summer, but all the varieties seem to need more sun than I've got. I'm looking for ideas for any tall (5' or more) leafy tropical looking plants that could take mostly full shade. (Total space to fill is 20' by about 5'.) Any help appreciated!
