From the photos that I have seen of it you are right, Caitlin. Some photos show more peach and some less, some show it with more blue and some with more lavender. What a fun thing to grow such a beautiful iris and see what it wants to be in your own garden.
I had a little one like that bloom this year. A little SDB named Sand Song. I had seen photos where it was muddy and some with just colored lines. I had hoped for it to bloom with more of the color that is on the Winterberry web site and it did. I am not a good photographer but this is a little bit of Sand Song
