These woody-stemmed plants can be pruned in fall or early spring to within a couple of feet of the ground, and will vine up fence, trellis, arbors (or other plants) to heights of 10 to 30 feet. Clematis ternifolia can also be allowed to sprawl along the ground as a dense ground cover. Blooms on new growth. No serious insect or disease problems.
