Shade tolerant plants for Tucson?
I live in the Armory Park downtown neighborhood of Tucson and have a north facing patio area with two ~8x8x10 triangular planting areas that get very little sun (at this time of year they get no direct sun). The two sides of each planting area are the walls of the house and a porch, the third border is a concrete/brick patio. I am able to amend the soil easily and irrigation is in place but currently capped. Whatever I plant I'd like to survive the winter (zone 8). I dont mind wrapping for the winter if necessary.
I had originally wanted to plant a small patio tree perhaps with some potted tropicals/annuals underneath but I think the sunless issue might prevent this. I am thinking of possibly banana plants?? Shade tolerant species of bamboo? Ferns maybe? What other ideas might you have? These areas will be closely viewed when sitting in the patio with glass of wine in hand.
