An outdoor plant wall, also known as a living wall or vertical garden, is a vertical garden that grows plants on a wall or other vertical surface. These walls are designed to provide aesthetic appeal, improve air quality, and create a green space in urban environments. They are typically made with a variety of plant species, and can be constructed using different materials such as moss, sedum, or other drought-resistant plants. Outdoor plant walls are popular in modern architecture and urban design due to their ability to integrate nature into urban settings.
