Water Efficient Plants

Water efficient plants are shrubs, perennials, succulents, groundcover, grasses and trees that thrive in San Diego’s Mediterranean climate and need less water than cool season turf. How much water a plant needs—it’s water use — is described as a percentage of how much water cool season turf needs.  Replacing cool season turf with moderate water use plants, for instance, can reduce your irrigation needs by 30 percent.
