Bonnie - I think it is more number of irises you have because you collect the hybridizer's iris. Your issue with Willott iris is the same I have with Pinkston. Like them, but very hard to come by. Greg, on the other hand, has been successful in collecting many of Innerst's iris - and so he has mort of Sterling's iris than other other hybridizer. If Burseen made a bunch of crazy SDB's to go with his TB's I might have gardens full of his blooms.
