Start here, at our original demonstration garden. Planted in 2014 and fully mature, it’s a vivid example of how you can convert your ordinary lawn into a stunning water-efficient garden using drought-tolerant, California-native, and fire-resistant plants. Signs explain how to pick the right plants, install the right irrigation equipment, and set the right watering schedule.

Kurapia is a highly versatile, low-water, and walkable alternative to turf. It can be mowed and manicured to resemble a traditional lawn – or left as a billowy groundcover with delicate flowers. Fast-growing and easy to maintain, it can be grown under many harsh conditions including extreme weather, slopes, and areas of heavy foot traffic.

Our kurapia was planted in June 2021.

This is our newest garden — planted in late July 2022. California native plants are beautiful, low-maintenance, and adapted to our local rain cycle. There are thousands of varieties to choose from – everything from trees and shrubs, to grasses and succulents. Butterflies, bees, birds and other important pollinators will want to call your garden home. No plant is better adapted to our climate than those that are found here, naturally.

Come back each season and to see how this garden grows in!

San Joaquin Marsh

demo_marsh.jpgTake a trip to the San Joaquin Marsh Wildlife Sanctuary – a hidden gem in Irvine. The demonstration garden surrounding the Visitors Center has more than three dozen plant varieties, each identified with a plant marker and QR code for mobile access to plant-care details. California-native and non-native drought-tolerant plants are featured in two distinct sections of the landscape.

Interpretive signs show how they differ in their growing characteristics and water needs. Additional signs illustrate how efficient irrigation technology and scheduling keep the garden looking healthy.

A stormwater bioswale, consisting of river rocks and stones, runs prominently through the demo garden to collect rain or irrigation water, helping it seep into the ground instead of running off-site. 

The San Joaquin Marsh Visitors Center is located at: 5 Riparian View, Irvine
