Brad Collins is someone you may have heard of. He was the subject of a World of Irises post “Aruba’s Eye-Popping Clump Shots” featuring his photography of great clump shots in his previous garden. Now he has a much larger garden in rural Des Moines where you will see over 500 bearded guest irises. In addition there will be thousands of seedlings from his hybridizing.
Now is a good time for you to see thousands (almost 4000!) of his iris photos here. Warning: There are 200 pages of addictive iris photos!
Update: Here are two more threads from him where you can see some of his seedlings and other photos. This one had 57 pages when I checked and his newest one had 4 pages.
