For a modern and sleek look, opt for a metal arbor with climbing roses in your courtyard garden. The clean lines and minimalist design of the arbor will create a striking contrast against the softness and elegance of the roses. The metal structure can be painted in a bold color to make a statement or kept in a neutral tone for a more subtle effect. The climbing roses will add a touch of nature and beauty to the contemporary setting, making it a visually stunning addition to your outdoor space.
