Thanks everyone for your info. I did google Iris psuedacorus and I am sure that is what I have. I will continue to remove the seed pods to keep this plant from overtaking everything else.

Thank you in the name of the environment. Those pods will float.

I cut the foliage back on mine even I am going to replant them right then. The purpose of that for me is too allow the plant to develop a root system to hold itself up. If I leave the foliage it is usually top heavy, falls over, gets blown over and then I have to keep replanting the silly thing and it lays there and dries up!

they are invasive in many states and banned from sale.

That makes perfect sense, Lily.

New plants of them is illegal here & we took out our old plants, although that is not necessary.

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.
