The Seven Principles of Xeriscape

Xeriscaping continues to gain popularity around the world as people discover the benefits of this landscaping technique. In Latin, xero means dry and scape means landscape or view. As an official landscaping technique, xeriscaping seems to have ‘originated’ in the 1980’s as a result of ongoing, multi-year droughts plaguing the Western, United States, but people have been planting to match their climate for centuries.

Landscapers–from California to the Rocky Mountains–were seeking a way to create gardens less dependent on irrigation without sacrificing aesthetic-appeal. , the largest and oldest public water utility in Denver, Colorado, coined the term and began to formally define the main principles of xeriscaping for members of the Denver community interested in modifying gardening practices to save water. Though it began in an effort to engage in water conservation in dry areas, it evolved to include a broader set of goals captured in the guidelines below.

Seven Principles of Xeriscaping 
1. Sound landscape planning and design.
2. Limitation of turf (commonly referred to as lawn) to appropriate, functional areas.
3. Use of water efficient plants.
4. Efficient irrigation.
5. Soil amendments.
6. Use of mulches.
7. Appropriate landscape maintenance.


Xeriscaping doesn’t just have to be for arid climates. These principles can be implemented in all ecoregions and lead to positive outcomes like reduced weeds, the creation of dense native plantings, less yard maintenance, minimized use of pesticides and fertilizers, and reduction of non-native lawns. In an attempt to understand why people choose to engage in xeriscaping, researchers in Saskatoon, Saskatchewan, Canada identified two neighborhoods with homeowners that had engaged in xeriscape landscaping.  Twenty families were interviewed regarding their choices for their yards, their motivations, and the consequences of their gardening choices. They discovered water conservation took a back seat to aesthetics and the joy of gardening as the primary motivations for adopting xeriscaping principles.

The results of this research show that households with xeriscape landscaping were motivated mainly by factors related to landscape aesthetic and physical activity rather than water conservation.

Must I use native plants for xeriscaping?
Notice that using native plants is not specified in the principles of xeriscaping. However, many gardeners do embrace using native plants in their designs. Why? The simple answer is native plants are better adapted to the regional climate variations than non-native plants. This often results in native plants success without excessive watering, fertilizers, or pesticides. Ecologically speaking, native plants are also thought to provide more beneficial habitat for wildlife, making them an excellent choice to support the birds, bees, butterflies, mammals, amphibians, and other creatures that share our neighborhoods with us. Homeowners can design xeriscape gardens with non-native plants, but our recommendation would be to exhaust native plant options first.
