Everyone has their favorite books. These are some of mine.
Peterson's Field Guide	Peterson's is the field guide I use most often. Unfortunately the plants are represented with illustrations and not photographs. This book goes with me everywhere and was used to identify the wildflowers found on my site.  The National Audubon's field guide is filled with photographs and makes a great companion to Peterson's guide. For ease of use I prefer the Peterson guide, for the photos alone I would recommend the Audubon guide	National Audubon
If you decide to purchase a field guide make sure it is for your region.

If you see a beautiful garden you can be sure that there is a collection of gardening books somewhere in the owner's home. I am no different.
I love this book for the photographs. Over 1500 plants are covered. I almost want to move south after looking through this book.		Enough information is presented with each plant to get you going on cultivation. This is a great book to use when making a wish list.

	Rodale's selection of gardening books are amoung the best. When it comes time for a reference, look to Rodale for an informative book. These are two of my books from their garden experts and the pages are getting pretty frayed.
These are the books that I use constantly, others are piled around the house. If I was limited to only a few- the 5 books above would be my choice.
