Iris Fan question
I have been growing Iris for a few years and over the years have added different colors just to see them bloom. I don't keep up with names or any of that. A few days ago I got a mess of fans from an older lady that told me something about them and I was curious whether it was true or not.She said that if you look at the back of a fan at the bottom of the stem if it has a purple color to it it's most likely going to be a two-tone color. Does anyone know if this is true? I checked mine and I have alot with this color on them. Because most of them I bought last year they didn't bloom this year so I haven't even seen the bloom colors.
