It can be frustrating.... I had to confirm with the hybridizer's daughter that PINKITY had PBF, because it wasn't registered or listed as such in the AIS database (because the hybridizer thought it was not pronounced enough to be worth mentioning).
I have an iris I bought for the name, LOVELY LOIS, which I will forever wonder if it is true or not, because the data base says it has PBF, but I don't recall ever seeing it on my plants.
