Xeriscaping (often incorrectly called zero-scaping or xeroscaping) is landscaping and gardening that reduces or eliminates the need for supplemental water from irrigation.[1]It is promoted in regions that do not have easily accessible, plentiful, or reliable supplies of fresh water, and is gaining acceptance in other areas as access to water becomes more limited. Xeriscaping may be an alternative to various types of traditional gardening.[2][3]

In some areas, terms such as water-conserving landscapes, drought-tolerant landscaping, and smart scaping are used instead. Plants whose natural requirements are appropriate to the local climate are emphasized, and care is taken to avoid losing water to evaporation and run-off. The specific plants used in xeriscaping depend upon the climate. Xeriscaping is different from natural landscaping, because the emphasis in xeriscaping is on selection of plants for water conservation, not necessarily selecting native plants.

Public perception of xeriscaping has generally been negative as many assume that that these types of landscapes are ugly or limiting. However studies have shown that education in water conservation practices in the garden can greatly improve the public's perception of xeriscaping.[4]
