I used some Whitetail Institute Powerplant last year which is a bleand of beans, peas, as well as sun flowers. The deer destroyed the mix and never let it get more then 3 feet tall. Out of aprox 200 Sunflowers that grew in the plot only one made it to seed. The rest were mowed down by the deer.

I'mm not sure how they will atract on their own but if planted in a blend they work very well to attract and the deer really like them.
