Late September through December is the best time of year to install a permanent, drought-tolerant landscape, and now is the best time to plan it. Many people are aware that the “traditional landscape” of lush green lawn with rosebushes and manicured shrubs was developed in England and regions of France that get more than twice the rainfall we normally do. While a typical lawn in our area requires about 57 inches of water each year, South County only receives about 21 inches on average. So whether your source of water is a well or the Sierra snowpack, this is not a sustainable landscape long- term, even if we do get a wetter winter than last year.
The current drought has forced us to look at low-water landscapes typical in Mediterranean climates. At least 50 percent of our current residential water use is for outdoor landscape watering. We can reduce this dramatically by converting lawn areas and thirsty plantings to those native to California, the Mediterranean region and other dry climates.
Your new water-wise landscape can also be a beautiful and interesting yard that attracts butterflies, birds, bees and beneficial insects. Many plants with varied foliage textures, colors and blossoms grow well in our Mediterranean climate, including drought-tolerant fruit trees and perennial herbs.
If you are not sure that a favorite plant of yours is drought tolerant, go to a new important tool—an updated list of plants called WUCOLS (Water Use Classification of Landscape Species.) The WUCOLS tool rates plants on water use from high to very low. This extensive project was supported by California Department of Water Resources, University of California Extension, and a host of professional organizations and experts in the landscape industry. The website is ucanr.edu/sites/WUCOLS/.

The WUCOLS list recommends these drought-tolerant plants for creating beautiful landscapes.
