Winterizing parsley

[Songbird]

My italian parsley finally did real well, and is actually still alive and growing, but now the weather is getting too cold to leave it outside.
Can I keep it growing all winter by bringing it inside?? What does it need?

Well, i think it's too late.
I didn't know it was going to get so cold overnight, and the poor parsley is frozen.

I'm going to pick it, bag it, and just keep it frozen, I guess. I think if I allow it to thaw, it will be ruined.
