I need help IDing a vine

I live in North Texas and have an unknown vine invading my holly bushes. Every spring since we moved into this house, a vine emerges from underneath one of the holly bushes. Until this year, my husband would remove it whenever it would show up. Since this back-and-forth is in its 6th year, I told him to let it go until we can figure out what it is. I've looked in several books/website, but have not been able to identify the vine. The vine has not attached itself to the brick on the house; it seems to just prefer snaking through the holly bushes. Any guesses? unknown vine unknown vine
