"Xeriscape" is not a synonym for gravel and cacti. The term — coined in Colorado in 1981 — describes water-efficient landscaping that uses plant selection, soil improvement, mulching, and efficient irrigation to significantly reduce outdoor water use. A xeriscape can include lawn areas, perennials, trees, and shrubs, as long as they are adapted to the local climate and irrigation is managed efficiently.

In the arid and semi-arid west (California, Nevada, Utah, Arizona, Colorado, New Mexico, Texas), the case for reducing or eliminating lawn is backed by real water economics. Per UC IPM, the average California home lawn uses 40—70 gallons of water per square foot per year — a figure that has become untenable in drought-prone regions.

The seven principles of xeriscape

Per UC IPM, the original xeriscape framework from Denver Water (1981) includes seven design principles:

1. Planning and design: Assess existing microclimates, sun/shade, and water needs before planting
2. Soil improvement: Amend with organic matter to improve water retention in sandy soils and drainage in clay
3. Appropriate plant selection: Use plants adapted to local rainfall patterns without supplemental irrigation
4. Practical turf areas: Reduce lawn to functional areas (play, recreation); replace decorative lawn with alternatives
5. Efficient irrigation: Drip irrigation for shrubs, mulched beds; smart controllers with rain sensors
6. Mulching: 3—4 inches of organic mulch to reduce evaporation and weed pressure
7. Appropriate maintenance: Systems designed to reduce long-term maintenance inputs
