I recently moved and the new house has an Ivory colored brick. What I need to do is create an area for my wife to have some flower beds around the house. She knows she wants mulch, and I know I want a wall or edging of some sorts that is easy to mow around. Do you guys have any suggestions what I could use (color is mostly my concern) to make a wall or edging that would look good with Ivory brick? Thanks in advance, John.
