Leslie, I have absolute Treasure, and it's a wonderful blend of light sky blue and white. One of my top favorites, possibly my most favorite. But I was entranced by photos of Caroline de Monaco. It's a Cayeux iris and i gather it has not been well distributed in the U.S.
Lucy is in Massachusetts. Perhaps it doesn't thrive well that far north. Does anyone in the mid-Atlantic area have it, and if so, does it perform better there?
We had a prior discusdion in which CdM was compared with Sky and Sun, and one person said that of those two, CdM was much, much prettier.
