I cannot say a hybridizer is my favorite by the numbers I have because I really have gone by the bloom I want more than who created it. I love Lucille Pinkston's iris, but doubt I will ever be able to get more than two of hers as they are very hard to find. I really like Burseen's iris, but don't think I will ever collect them all.
In other words my numbers would be misleading!
