Landscaping designed specifically to require less watering than most landscape designs.
Xeriscape (the Greek root "xeri-" means dry) is especially popular during droughts, in arid and semiarid areas, and among those who try to be environmentally friendly.
Succulents like cactus plants are used in some, but not all, xeriscapes. Careful planning can give you a beautiful landscape that just happens to look good without being watered every day.
