I like this book very much! It is a great source of information about plants, trees,shrubs,flowers (and more),to be found in San Diego and surrounding areas. There are numerous helpful photos.I consulted this book often while considering what to plant around my home in the Julian area. It is a fantastic reference book, and I probably refer to it now on a weekly basis.I purchased it at the Anza Borrego Natural History Asso. store in Borrego.
