For a classic and traditional look, opt for wooden fences as courtyard garden dividers. Wooden fences provide privacy and create a cozy atmosphere in your outdoor space. Choose fences with lattice or trellis designs to allow climbing plants to grow and intertwine, such as Jasmine or Clematis. Pair the wooden fences with ornamental grasses like Panicum or Stipa for a natural and relaxed feel. The grasses will add movement and texture to the fences, creating a visually appealing courtyard garden. Additionally, you can also incorporate hanging baskets or planters along the fences to further enhance the beauty of your outdoor space.
