Hanging garden

A hanging garden is a form of sustainable landscape architecture that can take several different forms, such as roof gardens, but is generally defined as a garden planted at a suspended or elevated position off the ground. These gardens are created with walls, fences, planted on terraces, growing from cliffs, or anything where the garden is not touching the earth. Space optimization is the main intention with the gardens, with aesthetics and providing cleaner air also commonly cited reasons. Hanging gardens are popular in urban environments with limited space such as in New York City or Los Angeles.
