You can plant a Mermaid rose and bet your life they won't eat that :) But it is a monster of a rose, can sprawl quite a ways if left unchecked. Cows get to everything at my place, they leave the Mermaid alone.
Alternatively, you can make a border of Yucca and plant inside that. I live in Bryan, right down the road from you. Some rural people have done that. It's a great deer deterrent.
