Gardening is now the favorite outdoor leisure activity in America. Homeowners realize the health benefits available from gardening and the potential increase in their home's property value.  Regional gardening titles offer the most useful advice because they provide credible information on the plants that perform best in specific states. Gardeners want information they can trust and use successfully in their own gardens.  The Arizona Gardener's Guide is a full-color plant selection resource guide written especially for Arizona gardeners. It includes the top 175 landscape plants as recommended by one of Arizona's most respected horticultural experts.
