Chinese artichokes in Zone 4?

I grow almost exclusively perennials and I'm looking to add this fun plant but what I've seen days they're hardy to zone 5.

Sunchokes, both red and white, do well here as does every mint I've tried. Do you think chinese artichokes would make it?  What's a good source for getting rhizomes?

No experience with chinese artichokes, but if it turns out they don't make it, they have an European cousin called marsh woundwort (Stachys palustris) that can be used the same way (tasty!) and is quite hardy. Grows very well indeed in north Swedish long-winter zone 5. Would guess it'd do ok in zone 4. Good luck!

Thanks. That sounds like a good backup
