My in-laws have an incredible native garden in California that is beautiful enough to have appeared in a couple of publications as an example (this is not some extravagant and rich family either, by any means). They rarely have to water their garden, compared with their neighbours who seem to have to hose/sprinkle their lawns every other day, practically.
