This wonderful garden has four miles of garden trails on 37 acres of what use to be a farm. It began as "Quail Gardens" in 1971 with many water smart gardens. In 2009 the name was changed to San Diego Botanical Gardens. San Diego County no longer supports it, rather it is operated by a non-profit organization. It seems to me that any garden in California will be successful because the state is one of only five small regions in the world with a Mediterranean type climate. According to information provided by the garden, California has 4,300 species of flowering plants. And not only did the plants delight us in the garden, but also many butterflies and hummingbirds. The latter especially like the weeping bottlebrush tree.
