The back of our property has a retaining wall about 3 feet high. There are mature maples and tons of shade there. Our house really needs to have some privacy from the house to the left. Behind us is a driveway to another home, and at night the headlights on cars come right in the rear of the house.

I am thinking of putting in some kind of evergreen for a privacy barrier. Any suggestions? I'm not a big fan of arborvitae. Would holly work here, or any other thoughts?
