Oh good job, Arlyn! How very clever of you -- and I'm sure that will work a treat!!! What gauge wire did you use?
Last year I didn't find homes for all of the rhizomes that I'd dug -- and a small assortment lay on the ground around a bush under the Birch tree. By Spring, they had all grown roots and put up leaves. They're still there -- I expect they'll bloom next Spring!!
Moral of the story -- if the temperatures cooperate, most Irises will go ahead and set roots almost regardless of how late they're planted. And some of them -- regardless of whether they're planted or not!! At least -- that's been my experience.
