Don't think they grow in the frozen tundra.

They grow in zone 5-10. You could overwinter the roots indoors and replant in spring. They are prolific and can produce the first year.
Now that I did not know. The only place I have seen them is Hawaii. Maybe my zone 8 will work...
They’re native to the continental US. They’ll definitely grow where you are. If the root cuttings work out, I’ll start selling them for shipment.
This is the hardest one I’ve seen
