I use the Iris Encyclopedia to find information on iris pictures which come up on random plants. A picture just came up of Pagan Pink. When I clicked on it there was little information. I went to the Encyclopedia and found that it was a Byers Iris from the 1980's. I enjoy seeing that info. Sometimes I add that info to the ATP data base.........is that helpful? With limited space in my garden I prefer to grow newer named varieties...
