Is there such a service as a website for peony photos similar to the Hosta Library? That site helps greatly in identifying hostas or verifying that you have what you think you have.
Individuals can send their photos to the web host for possible inclusion. I myself have sent in photos for hostas that were not represented at all or where I thought the existing photo/s were not very good photos. Also, when you see a gorgeous perfect picture in a catalog and think "I've got to have that one"... sometimes when you look it up on the Hosta Library you find a variety of pictures from different gardeners and discover that it doesn't always look as great as the catalog photo!
