Just that really, I’m not too keen on crinkly savoy type cabbages but can’t identify a smooth winter cabbage. Thanks for any advice.

I don't think so.  the best is probably Tundra, which is still a fair bit crinkly. It's like a semi Savoy. I assume the crinkly Savoy leaves means that it can expand and contract when frozen better than a ball head which would split.

Thanks, that makes sense. Tundra it is then.

Besides Tundra, I've also grown Marshall's Winter Green but that's a pointy one
