A garden arbor is a structure typically made of wood or metal that is used in gardens or outdoor spaces as a decorative element or to support climbing plants, such as vines or flowering plants. It usually consists of a framework with an arched or flat top, often with lattice or crosshatch sides for plants to grow on. Garden arbors can serve as entrances, gateways, or focal points in a garden, adding visual interest and creating a charming and inviting atmosphere.
