Ornamental grasses are a versatile and low-maintenance option for courtyard garden dividers. These grasses come in a variety of colors, textures, and heights, allowing you to create a unique and visually appealing divider. Ornamental grasses can be planted in rows or clusters to create a natural barrier between different areas of the garden. They add movement and texture to the space, as their leaves sway gracefully in the breeze. Some popular ornamental grasses for dividers include fountain grass, feather reed grass, and maiden grass.
