Of the estimated 29 billion gallons of water used daily by households in the US, more than 8.5 billion, or 30 percent, is devoted to outdoor water use. In dry climates, a household’s outdoor water use can be as high as 60 percent! The majority of this is used for landscaping. Native plants are a water-wise solution. Once established, native plants selected for your climate and soil type require little water other than normal rainfall.
