Garden walls can be a tricky part of backyard design. At best they're functional; the walls of your house, a retaining wall for your flowerbeds, or the edge of your property. At worst, they can be eyesores, exposing large expanses of boring brick.
This problem gets worse in winter when darker nights hide the walls. Even if you have walls with a little pattern or color, the night will turn them into dim monoliths that don't add anything to your yard
