Resilient no-water gardens are not instant gardens. We are so used to the idea that landscaping means clearing a plot, buying a load of plants with lush foliage and sticking it in whenever, and then irrigating to keep everything alive. That approach is the result of an industry that needs to sell plants and work year round. But running out of water brings that model to its knees. The no-water way is necessarily seasonal, slower and more local.
