Helix's Demonstration Landscape

We built a new Demonstration Landscape at our administration office in La Mesa. It beautifies the neighborhood and inspires, we hope, WaterSmart landscaping in all the neighborhoods we serve. Installing a WaterSmart landscape is a big upgrade for your property, and we have the resources to help you.

3 Streets, 3 Gardens

Our University Avenue garden features plants from the world’s Mediterranean climate zones. The Lee Avenue garden showcases desert plants and Palo Verde trees. And, the Quince Street garden demonstrates the casual beauty of plants and trees native to California. The plants in all three of our gardens are right at home in San Diego’s climate. They can thrive on half, a third or a fifth of the water that a traditional lawn needs. You can save an enormous amount of water and save money on your water bill, too.

We Made This Easy

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.
