Set in the heart of the city, the Tucson Botanical Gardens offers plenty of winding pathways, taking visitors past floral exhibits, greenhouses, classrooms for instruction, and a superb exhibit on xeriscaping, a concept of planning yards and gardens using minimal water in the desert climate. Don't miss the iris garden, the herb garden, the unique tropical exhibit or the well-stocked gift shop. The garden regularly hosts special events, such as music in the garden, a butterfly exhibit, and a special luminaria event during the winter holiday season. Whimisical and informative, the Tucson Botanical Garden offers visitors special insight into the plant life of the desert.
