We just built a garage and I'm trying to plan a border along one side. It faces East with lots of sun and will get a little afternoon sun too. The garage/bed is about 20 feet long . I will probably have the border/bed be about 6-8 feet deep. I really want to plant Limelight hydrangeas but wonder if I should incorporate any evergreen with it so it isn't bare in winter. I'm interested in a mass type planting because this border will be viewed from a sidewalk that is 50-60 feet away. What about an "anchoring tree " in the corner? It would have to be a dwarf variety. The garage is white.......Any ideas?
