sundial - fast growing vines to conceal it

I almost bought a sundial yesterday. But, I was too late by the time I had the money in hand. I was thinking one would look good in a herb garden. I moved the flagstone to the area and we have a fence of sorts. I am wondering, since we won't get frost until November, is there a fast growing vine other than morning glories that I can plant on a wire fence to sort of conceal it. Dooley
