Vine usually means a plant that has a weak and flexible stem requiring some kind of support. Some vines can climb walls, trellises, or other plants. Other vines creep along the ground. Some vines have tendrils, which wind around their support. Other vines have disks that cling to the object they are climbing. There are two important kinds of vines–woody vines, also called lianas, and herbaceous vines. Grapes are woody vines. Sometimes the woody vine is fairly short and can support itself. Then it is somewhat like a shrub. It is often difficult to tell the difference between such a vine and a shrub. Common kinds of herbaceous vines include cucumbers, garden peas, and beans.
