They look more like cabbages to me. BS should have a stalk growing up.

Yes, they are better after a frost.

They look like Brussels sprouts to me, based on leaf shape and petioles, although rather dumpy. They do need a long growing time. Are there any baby sprouts forming up the stalks? If they were mine I’d probably give up on getting any sprouts and harvest those tops whole. They’re absolutely delicious. They’re sold over here as sprout tops and to my taste they’re better than the sprouts themselves.
