I know, sooooo many beauties! I just got Tropical Shoals this summer but I have seen it in a garden in south AR and yes it is a light blue that leans to turquoise in color. If it blooms this spring, should I say when it blooms this spring, I will take photos and let you know its color in my garden. I got Teagan, Tropical Shoals, Miss Meredith and Blues Clues to see if I could introduce some turquoise blooms in my garden. I was sent Rich Blanquet as a bonus and I think it is also in this color range. Once Winterberry knows what you are looking for they will discuss the irises that may fit your wishes and bonuses will be in that category also.
The problem for me is that they are creating sooooo many more beauties every year! and I cant have them all!
