"Decorative" grass that doubles as rabbit food?

I'm looking through seed catalogs today. I'm looking for a "decorative" grass that I can feed to rabbits. I'd like something 3 -4 feet tall. Taller is OK. Partial to full sun.

How about borage? Bees love it too! Not really a grass, I guess...but pretty all the same.
