Try and put them somewhere well drained, cold damp tends to do the damage in the UK, combined with lack of summer heat, rather than just winter cold.
I'm tempted to try again sometime, I may let them grow in the polytunnel though, if I can find a space for them.

They will still be very pretty, wild ones usually are very beautiful. Yes they will still produce edible rhizomes as long as they are canna "edulas".
As far as your winters, you are right on the border... You might lift them out to divide them. Eat some, plant some out in spring. You could heavily mulch a couple and see if they make it okay.
