Honestly, I would plant nothing in there that will attract deer. If you do it, it will start a feeding pattern that you will never break until you fence it in, or take other drastic measures. If you don't have the headache of trying to keep them out of your garden, then don't start by inviting them in. If they are already eating your garden and you don't care then I would plant something like winter peas, wheat, rape or oats.
