Moved into a new house in Pittsburgh, PA. Zone 6. The front of the house faces North. The previous owner did not keep up on the shrubs and I have removed the shrubbery that was near the steps. The pictures show some type of ground cover that I am in the process of removing also. I would like ideas on different shrubs or perennials to plant. Also, I was thinking of a tree in the middle, but was not sure of what to plant. Thanks!!
