Xēros is the Greek word for "dry" that is the base for a handful of English words related to mainly dry printing ("xerography") and dry, or xerophilous, habitats and their plants. In the early 1980s, the Greek adjective was used to name a type of landscaping practiced primarily in the arid western regions of the United States. (The Water Department of Denver, Colorado, is credited with the word's coinage.) "Xeriscape," as it is called, uses plants that require little water and techniques that efficiently use water and reduce evaporation.
