That shrub border runs along the entire south side property line and totally screens out my neighbors driveway. In the summer you can't even see thru it and when you come around the house to that part of the garden, it looks like a woodland edge. That is the effect I was going for. Also to attract lots of backyard songbirds with the fruiting shrubs that had berries for the birds to eat.
Woodland edge, then grassy path, then roses and lily bed running along side the house. It all turned out very pretty.
That rock there is just stacked loosely, no mortar so its just for effect to define that shrubby area.
