Metal trellis panels are another great option for dividing a courtyard garden with ornamental grasses. These panels are not only functional but also add an artistic element to the space. They can be used to create a focal point or to define different areas within the courtyard. Ornamental grasses can be planted around the trellis panels, allowing them to grow and intertwine with the metal structure, creating a beautiful and natural screen. Metal trellis panels are durable and can withstand different weather conditions, making them a long-lasting solution for courtyard garden dividers.
