They're not just orange and yellow anymore. And the people who have created them and collect them are people you would like as neighbors.
Among the hundreds of gardening books I have read there are few that truly deserve the tittle, "Absolutely wonderful -- a great read." Sydney Eddison has never written anything but great, educational books that are good reads.
However, her daylily book is not just about Hemerocallis, it includes information about the people involved with daylilies, some history of the plant and how it has evolved. Did you know that the modern, hybrid daylily is essentially an American bred flower? Or did you know that most of the hybridizers have been - and still are - backyard hybridizers. Very few of them have had any training in botany.
While enjoying your read, you will want to meet and converse with the people in Sydney's book. After you finish it, do not be surprised if you end up looking for a local "Hemaholic" or Daylily Collector to find out how you can enjoy the beauty of the flower and the camaraderie of those involved with daylilies.
How could the book be improved? A publisher should sign her to write a new and larger book. My second choice would be a reprint of this book with at least a hundred pages of additional material.
If you can find a copy of this out of print book, buy it. It has become one of the most sought after gardening books.
