I have replanted many of the Iris rhizomes on my road bank. In the future I will be sure to cut the seed pods off before they dry up and open. I have a lot more of them that I am just going to dig up and throw. The ones behind the garage I want out of there so that I can plant double Hollyhocks in their place. I also have more of them in my raised bed which are going to be coming out of there so that I can plant other flowers there. Thank you all so much for your input on this invasive Iris.
