The Halawa Xeriscape Garden displays a series of xeric (dry) plants in a residential-scale setting to demonstrate species capable of providing a visually attractive garden, while using less water than most currently popular plants. It was opened to public in September 1989, after several years of effort by the Board of Water Supply (BWS), as a way to educate Oahu residents on ways to save water in lawns, gardens, and landscaped areas.
In these demonstration gardens, you can familiarize yourself with the kinds of plants and grasses that need less irrigation, as well as the variety of approaches that use water more efficiently in the garden. These approaches include irrigation techniques, cultural practices, and landscaping ideas that will provide for drought-tolerant gardens and landscapes.
Suggested cultural practices that can save water are also seen at Halawa. These include: mulching, soil alteration, turf mowing practices, thinning of planted areas, weed control, and fertilization.
The Halawa Xeriscape Garden is closed until further notice due to the coronavirus pandemic.
The Halawa Xeriscape Garden is located in Halawa Valley's Central Park Industrial Area.

The Halawa Xeriscape Garden hosts workshops that generally include instruction on how to xeriscape, efficient irrigation, propagating native plants that save water, soil improvement/mulching, lei-making with xeriscape plants, and wreath-making with xeriscape plants, among others. Sponsored by the Friends of Halawa Xeriscape Garden and the Honolulu Board of Water Supply, these workshops are generally scheduled on Wednesdays and Saturdays.
As of July 2014, the BWS no longer offers free mulch at the Halawa Xeriscape Garden in order to align with statewide efforts to prevent the spread of invasive pests. Mulch piles are potential breeding sites for the Rhinoceros Beetle, an invasive scarab beetle that feeds on coconut palms. For alternative free mulch giveaway sites, check with the City Department of Environmental Services (ENV).
