What is the name of a structure that supports climbing plants and serves as an aesthetic screen?

A trellis is specifically designed as a support for climbing plants and serves as an aesthetic screen in landscape design. It typically consists of a framework of horizontal and vertical slats that allows plants to grow up and around it, creating a visually appealing green structure. The use of a trellis can enhance the beauty of gardens and outdoor spaces, providing not only support for flora but also adding texture and depth to the environment.

In contrast, a pergola is a larger structure that provides partial shelter while supporting climbing plants, often used as a walkway, passageway, or a sitting area. An arbor is a similar, but usually smaller, structure often defined as a nook or gateway but not primarily an aesthetic screen. A gazebo is a freestanding structure that provides a sheltered area suitable for sitting or entertaining but is not designed specifically to support climbing plants.
