1. An environmental design of residential and park land using various methods for minimizing the need for water use.
2. A trademark used for a landscaping method that employs drought-resistant plants in an effort to conserve resources, especially water.

A word coined by combining xeros, Greek for "dry", with landscape, which is a water-conservative approach to landscaping.

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.

Xeriscape is a trademark created by the Denver Water Board. In some areas, the term xeriscape has acquired a negative connotation (some have derogatively or ignorantly called it "zero-scaping") and so terms; such as, "drought tolerant landscaping" and "smart scaping" have been substituted.
