Clematis terniflora is a vine with opposite, pinnately compound leaves, on climbing stems. Wonderful! Flowers White, fragrant, four-petaled flowers appear in the late summer through the fall. In late fall the fertilized flowers become fruit (seed) clusters of 5-6 fruits connected at the heads and each having a long white tail. Foliage The leaves are opposite, compound (with 3-5 leaflets), and the margins are entire. Clematis vitalba: sepals tomentose adaxially, leaf margins entire to crenate or dentate, and flowers with 20 or more carpels (vs. C. terniflora, with sepals glabrous adaxially, leaflet margins entire, and flowers with 10 or fewer carpels). Clematis terniflora is a climbing, semi-evergreen, ornamental vine. It commonly overgrows saplings and small trees, killing some. Prune to 1-2' tall in early spring as leaf buds begin to show, removing all dead stems above the buds. The leaves are a leathery dark green. Fruit Seeds are also showy and production is prolific. The genus name Clematis is from the Greek word "klematis", for climbing plants. (5-7.6 cm) long. Clematis virginiana: X Close. Leaflets are each 2-3 in. It blankets native vegetation and eliminates the basic source that plants need to make energy – sunlight, smothering vegetation beneath it. Clematis terniflora, in addition to sweet autumn clematis, is also called Japanese clematis because it is native to Japan and China. The flowers are white, borne in fall. The blooms are nicely fragrant and visited by bees.
