I'd like to find an evergreen to anchor my border. It is fairly narrow between my house and the neighbors. It gets mostly morning to early afternoon sun. I've got a couple of full sun plants nearby (roses, tomatoes) that do fine there. The soil retains water well there (clay and no hot afternoon sun). My ideal plant would be a bluish evergreen about 6-8 feet tall and about 4 to 6 feet wide. I was thinking of a blue spruce, but I would need a small one and it really can't get too wide (6 feet means my husband curses me when he mows). Would 'Blue Globe' be appropriate? It was the only one I saw at the nursery that fit my requirements.
