Ok, here are some lists of native plants that
can live with no extra water after the first summer. That is, REALLY
drought tolerant or drought resistant plants for a California garden. A
landscape can look good and use little or no water.
We've planted many landscape gardens in winter with no watering system
no water after watering the plants in at planting. Watering once every
or two for 10 minutes generally makes a landscape look a lot better in
summer and renders most of the plants more fire proof than 'normal'
You can use many more native plants for each area but you'll need to
a little more winter/spring water to see a larger list, BUT, the plants
will not be as drought tolerant.
