AKA Dry shaded area. Aside from Cast Iron Plant I can't find anything to grow in a dark corner of my yard. And now that the Cast Iron Plant has filled in the front of the bed, I need something taller. The bed is full shade about 10 ft wide with about 3 mature trees nearby, hence the shade and the need for drought tolerance as the trees suck up most of the moisture in the soil. Hostas need too much water. Is there a tall variegated variety of Cast Iron Plant? How about a tall variety of Mother In Law Tongue?
