They overwinter here-
in my experience, prune them pretty short, almost close to the ground.

I have several in my garden, all volunteers. If I just yank one out, without pulling the roots as well, it just resprouts with the most beautifull fresh foliage.
The older ones tend to get some kind of rust and look ratty after flowering.

Now is the time of year to rip them up anyway, and I would bet they have already dropped seeds that will germinate next year. So watch for those to sprout and transplant them to where you want snaps.

Many of them overwinter for me as well. I have moved around the ones with colors I like best, often in the middle of summer even. They seem quite resilient with transplanting. I'd but them back to a few inches. Good luck!

Even in my zone 5, I usually get most of my snaps to over winter. The plants that return bloom much earlier than the new seedlings. I agree with the others that you can trim them back and move them where ever.
