I am looking to revitalize two garden beds that are separated by the front main stairs of a house. Each side of the stairway is a bed of approx. 7.5' x 16'. There is a window that is approx 3-3.5' above the center of each bed. Looking at some bushes that with minimal trimming will not overtake the windows and then something small in front of that intermingled with some annuals. I am located in zone 7. By the way the house is a red brick with white columns at the stairway. Thanks in advance.
