That doesn't really look like a clematis root. Perhaps it is something from the oak. But if you want to see if something will grow, cut off the section that is attached to the smaller roots and plant it in fertile soil in full sun, away from the oak tree. Keep the soil moist. Here is more on growing clematis.
