One of the most useful and beautiful books on roses I've seen. The author has been maintaining a large (5 acre) rose garden in Ohio for many years, trialing thousands of varieties of roses. In this book he shares his experience, describing how the roses performed, looked, smelled, and succumbed or didn't succumb to disease. He discusses each rose's faults and merits with brutal honesty, and there is an emphasis on garden performance, and how to site a rose properly for best effect and health. His favorite roses go well beyond the typical selection of wimpy hybrid teas, and include OGRs, species roses, modern shrubs, and many many more. The book is filled with large, beautiful pictures throughout. This book will probably be most helpful for gardeners from a similar climate to the author (upper and central midwest).
