Can I prune the top off ornamental cabbage?

I'm guessing yours has now bolted (flowering?). Well, not really. Technically, Brassica oleracea is a sub-shrubby perennial but selected clones tend to die off. Just chuck it or eat any healthy leaves before you do.

No, not unless you want to lose the actual ornamental part!
