Keep in mind that all plants require water, light, and nutrients to grow. There are however, some plants that need little water or can go for extended periods without watering (once established). These are what we call “drought- tolerant.” plants. There is a relatively new concept in landscape design called “Xeriscaping”. This is choosing plants that will survive on only the natural water that is available to them. These plants should be grouped together in a dry sunny area of your garden.
