Sweet autumn clematis (Clematis terniflora) is a climbing, deciduous, ornamental vine that may climb to 15 to 30 feet in height and 6 feet in width. The leaves are opposite, pinnately compound leaves (2 – 3 inches long), on climbing stems. The blooms are white, fragrant, four-petaled flowers appear in the late summer through the fall. In late fall the fertilized blossoms become fruit (seed) clusters of 5-6 fruits connected to the heads and each having a long white tail. As these dry, the shade of the fruits fade and the tail becomes feather-like. In the spring the seeds detach and are dispersed by wind. Sweet Autumn Clematis is a remarkable outdoor plant and makes a perfect border. This kind of vine develops well on trellises, arbors, wires or chain-link fences.
