Query: An informative book

This is a very interesting and informative book concerning some of the plants you are most likely to see in California's semi-urbanized wild places... that is, you're often more likely to see these plants than native plants.However, only a limited number of plants are covered, and there are quite a few very common and highly invasive species that I wish she'd included. This is a compliment to the amount of information she provides about the plants that ARE in the book: where the plant came from, how to get rid of it, how it propagates, various musings of someone evidently quite familiar with the species, and more.Also, there are a number of species that only occur in southern California, so if you live further north like me, this information is not especially useful.
