A wall, either free-standing or part of a building that is partially or completely covered with vegetation is known as a living wall.
Living walls are the self-sufficient vertical gardens that attached to the exterior or interior of a building. They are thoroughly different from green facades (e.g. Ivy walls). In living walls, plant root in a structural support which is fastened to the wall itself. The plants receive water and nutrients from within the vertical support instead of from the ground. While in green Facades, plant receives water and nutrients from the ground.
