I took an iris rhizome from along the bike path in my town, I have to confess. I have to say in my defense that they never bloomed where they were as the riparian growth and grass had overcome them, and since I watched the city mow and spray and kill most of them with herbicide along with the wild rose, chokecherry and dogbane they were targeting for about four years, I thought I would save a few and see what they were. Only one of two survived their first really hard year after the herbicide. Then I had to move it here to my new place, and it grew alongside of other iris that didn't bloom the first year after being moved. This second year I had forgotten it, but it bloomed anyway. I think it might be Mrs Valerie West. What do you all think?
