Joanne sent me one of these books and I can assure you that it would be a great addition to your rose library. It's a large book (approximately 8.5 x 12 inches) and it's full of amazing photographs and useful information and advice. Although you might assume that it would be of special benefit to cold-weather gardeners, people in any zone will find pertinent information, particularly the sections on rose pests and diseases, which include photos of the damage they do.
