Gardening in a thirsty state like California creates unique challenges, but also encourages and allows for some beautiful results.
Take, for instance, the street trees along this block of Jackson Street in the Pacific Heights area of San Francisco. I believe they are a type of Arbutus, and take very little watering. Birds are attracted to the fruit and clusters of small greenish white flowers that appear in fall and winter.
One of the unique beauties of the trees, like their cousins the California native madrone trees, is the beauty of the bark.
Lush green lawns and weeping willow trees have their own beauty, but it's not a beauty suited to our Mediterranean climes. Luckily, there are equally beautiful plants for us to enjoy here, while saving our dwindling water supply.
