I found this book to be very interesting. While the author has not written this book for those in the US specifically, I enjoy her critique of each of these cultivars, the strengths and weaknesses. I appreciate knowing if a plant is a slow grower - but worth it (or not), that it is a good parent in the gene pool, which ones do not open fully, and which plants are fully hardy. And the photos are lovely. A very nice addition to my daylily book collection - one of the books that I *use*.
As someone new to gardening, I thought this was a good overview of daylilies in general, even though the book is slanted toward plants in the U.K. It offers a brief history of the species, general characteristics and genetics, some of the best of the species, different variations, and information about care and cultivation. Although some descriptions ("Eyes, Banding and other Markings") could have used better illustration, I think this volume gave me a good base of knowledge from which to explore the subject further.
