I purchased the lot beside my house and have cleared out the underbrush. I have an area about 80X60 feet that is shaded by a canopy of cedars and bois d'arcs. I am in Murfreesboro, TN and the ground is poor with a good deal of rock. I am looking for ideas for plants to put around the edge for privacy and to define the area. I would like them to be at least 10 feet tall (over time) and it would be a bonus if they flower or have berries. Any ideas would be appreciated.
