I'm inclined to agree with Chuch that temp affects antocyanin. We had a very
mild winter last year and many of our true blue irises had violet tonings. I
found it even more pronounced on the warmer Adel Plains. I freind had some
Scented Bubbles growing that I recognised on form alone, it was distinctly
violet and yet this is one I regard as a true blue, almost a bit on the
blue-green side in some seasons.
