I have quite a large library of books on roses and I think that this is one of the best I've ever seen and one that I will refer to again and again. 2,000 roses are listed here in an A-Z format and it includes all classes of roses, including the recent David Austin and Romantica introductions. Unlike many rose reference books, this one seems to include roses familiar to us here in the U.S. (although I must note that the authors are British). Each entry includes basic info, like parentage, flower size, flowering habits, height/spread and hardiness. This is followed by a description of the rose and the type of climate it excels in. And, I'm happy to see that the authors have indentified individuals who have roses named after them and explains who they were! This information has always been rather difficult to locate. A photo of the rose is included and, for the most part, they are very good (there are a few that are so-so).
Other notable features are articles and sidebars that deal with the history of the rose, notable hybridizers in the profession and famous nurseries and rose gardens. A brief concluding section covers planting and caring for roses with good demonstration photos.
This is a big book, 448 pages, and one that will be very helpful to refer to when considering a rose.
