Let's not forget decorating the walls of our gardens, patios, and courtyards. If your garden does have one or more walls, then it is a potential opportunity to add another element of garden decor. Your vertical spaces are not only an opportunity but may also be necessary to help keep garden walls from being long blank spans.
For limited space, patios, courtyards, and small gardens where you might want a fountain, this example of a wall fountain like this is often the best option. Wall fountains can add the elements of sound, motion, and decor without taking up any valuable floor space of cramped and smaller areas.
