Tendrils

Definition: Tendrils are twisting, threadlike structures by which true climbers, such as grape vines or cucumber vines, grasp an object for support. Vines with tendrils will climb on their own, without being trained. In some cases, however, you will still want to tie vines to arbors, pergolas, latticework or other structures even if they do have tendrils, in order to cause the plant to climb precisely where you wish it to grow.
