This book was recommended to me by the Desert Botanical Garden when I first moved to Phoenix in 2007. It's difficult to find gardening books that apply to Southwest gardening. It's really a must-have for an Arizona gardner, as the gardening challenges here are unique.
The book is nicely broken out and tabbed into chapters like "Cacti, Succulents & Desert Perennials", "Bulbs, Corms & Rhizomes", "Palms", "Trees", "Shrubs", "Vines", "Roses", and you get the picture.
I like the fact that the book is nicely illustrated in color photos. It contains many segments by plant including helpful descriptions, planting instructions and growing tips, and zone information. We have quite a few climates in Arizona and frankly I was surprised when I moved here at the wide variety of plants that can be grown where I am located, in the low desert.
While there is a lot of information online, this is really an excellent tool for identifying native and non-native plants, and very helpful in planning a garden.
The author is very experienced with the unique range of climates in Arizona and understands the harshness and extremes that plants must survive.
An Arizona-specific, cold-hardiness, zone map is used in this book. Very accurate if you garden in Arizona. Not useful outside AZ
Each plant entry has specific zoning and good photos; bloom/color season, mature size, care and growing tips. The entries are arranged and color-coded into general plant types (cacti, grasses, trees, shrubs).
This is a good book for selecting plants to grow successfully in an Arizona Garden. Check the biblography for more books that address Arizona's specific climate
