I, uh, sort of lost them. I think I may have chucked them in the yard and mowed over them. I do have more that I haven't cut yet under my deck if you see yourself coming up this way anytime soon.
When I moved I dug up the root ball, put it in a bucket, and replanted at the new place. They're insanely hardy. So much so that some people consider them weeds. Crazy people, like my sister in law who drove herself crazy trying to get rid of them in her back yard.
