Thanks for the clarification, Bill.  The more I thought about it, seems
that changes in flowers (sports) from one clonal generation to the next
of irises would be more likely to happen than changes in basic growth
responses to nutrients or climate, which is what I was thinking about at
the time.  Totally making this up, but it seems like it would be in the
plant's best interest to have changes in flower color be fairly easy to
come by, but not growth responses.
