The design of a flower bed next to a wall typically involves creating a visually appealing and functional space. It can include considerations such as the choice of plants, the layout, and the materials used for edging and construction. The plants should be selected based on their compatibility with the wall's exposure to sunlight and wind, as well as their growth habits and maintenance requirements. The layout should consider the flow of traffic around the bed and the overall aesthetic of the surrounding area. Edging materials can vary from traditional stone or brick to modern materials like metal or concrete. Construction may involve raised beds or ground-level beds, depending on the soil conditions and the desired outcome.
