I'm getting a kick reading about the Pine pollen here. I'm guessing
that the first suggestion that it caused this was mutation was presented as a
bit of a joke? That's the way I took it anyway.
I am very impressed by the flower itself. It is amazing just how
different the two halves of the flower are. It is a window into two
possibilities that can result from exactly the same genetic makeup (perhaps with
some inhibitor turned on or off?).
Now if somebody was growing a piece of the "wrong" part that was producing
blue flowers, and if the label had come with it as being 'Being Busy', and if
that somebody posted a photo. We would all gang up and say "wrong!", but
in reality it would be quite correct! It would be a sport of 'Being Busy',
but still genetically it would be 'Being Busy'.
I wonder how often our "wrong" Iris are actually such sports. I know
it's a rare occurrence, but not unheard of.
