Scott Calhoun is an award-winning author and garden designer based in Tucson, Arizona, where he lives with his wife and daughter. Self-reliant prickly plants, in particular cactus, have long captured his imagination. In his design practice, he incorporates cactus into every residential space and sees them as the plant family of the future — especially in arid parts of the world. Scott is the author of six gardening books. His first book, Yard Full of Sun, was awarded the 2006 American Horticultural Society Book Award; his second title, Chasing Wildflowers, won the Garden Writers Association 2008 Silver Book Award. Scott writes a monthly garden column for Sunset magazine and you can catch up with Scott at ZonaGardens.com.
