😳 I have enough problems with "regular" iris sending surface and subsurface rhizomes in all directions (two weeks ago I cleaned up some rhizomes that had grown three inches onto our driveway — hard macadam!) that I cannot begin to think how I would deal with walking iris. 🙄
Yes, yes, they're very pretty, I know — why else do you think I put up with them? Oh, and Deb loves them, so there's that.
