The first step in creating a water efficient landscape is to get inspired and collect ideas. Experience how lush, shady and beautiful a fully-grown water efficient garden can be, read about gardens and listen to other gardeners.
Go to the Water Conservation Garden
The Water Conservation Garden is nearly six acres of themed gardens and exhibits. In our most recent survey, 57 percent of Helix customers who visited The Garden said they went home and used ideas from the garden in their own landscape.

See Helix's Demonstration Landscape
We built a new Demonstration Landscape at our administration office in La Mesa -- three gardens on three streets. Our garden on University Avenue features plants from the world’s Mediterranean climate zones. The garden on Lee Avenue showcases desert plants and Palo Verde trees. The garden on Quince Street demonstrates the casual beauty of plants and trees native to California and northern Baja. We built each garden right next to the public sidewalk, so you can enjoy them whenever you like.

We made it easy to learn about WaterSmart plants. Plant markers provide the name of each plant and, when you scan the QR codes with the camera app on your smartphone, we show you plant information. Learn how much water a plant needs, when it blooms, the flower color and its full-grown size.
Use Our Plant Lists
We made two lists of all the plants in the demonstration landscape. The first list separates the plants into categories to help you understand where they might fit into your landscaping plans. We also listed all the plants by number to help you interpret each of our garden plans.
