I recently asked our local hybridizer why he has not named an iris after himself. He said he cannot do that. I suggested that there are more ways than one to do so. Since his wifes name is Bessie and he has one named after her I suggested that he name one Bessie's darling or Bessie's dance partner. He liked the idea.
There is an article in the fall AIS Bulletin called 'An Iris By Any Other Name'. It gives the naming rules.
