In 1976 professionals from diverse plant-related backgrounds founded the Arizona Native Plant Society. They not only wanted to concentrate on native plants but also on Xeriscape, or dryscape, which is a garden that reduces or eliminates the need for supplemental water by irrigation. It stresses the use of plants that promote water conservation, they don’t necessarily use native plants. In a dry, arid landscape like Arizona, xeriscaping is a viable answer to conserving water. There are many local xeriscape demonstration gardens in Arizona. They provide practical, first-hand examples of plants and plant combinations. The Mesa Xeriscape Demonstration Garden is located on the Mesa Community College Campus is Mesa, Arizona.
