Summary
Clematis terniflora is a perennial vine that is frequently used as a landscaping plant. It is invasive, however, and displays aggressive growth in many areas of North America. C. terniflora can climb nearly 10 metres high, smothering trees and pulling down telephone poles.
Species Description
Clematis terniflora is a semi-evergreen climber or groundcover with semi-woody steps up to 4 inches. C. terniflora displays compound, opposite leaves, of 3-5 leaflets with a glossy, stiff appearance (Floridata, 2007). Leaflets are \"ovate or broadly lanceolate to narrowly deltate\" in shape (efloras, undated). White, monoecious flowers with 4 sepals on branching panicles. Flowers are bisexual or unisexual with in the same inflorescense (efloras, undated). Flowers are star shaped, highly fragrant, and approximately 3.18 centimeters across (Floridata, 2007). C. terniflora is an extremely showy flower in summer, to an exten that \"vines can be so laden with billowy masses of white flowers that they look like they're covered in snow\" (Floridata, 2007). C. terniflora's bark is initially smooth and light brown, later developing long splits and shreddy long strips\" (CNR, 2006)
Lifecycle Stages
Clematis terniflora is a perennial plant (CNR, 2006).
Uses
According to Plants for a Future (2007) Clematis terniflora is used as a folk treatment for corneal opacity. PFAF (2007) also notes that young shoots of C. terniflora can be eaten. C. terniflora is widely used as landscape ornamental. USDA-WOW (2007) notes that goats will eat C. terniflora but prefer it dried or dead.
Habitat Description
Like many climbers, Clematis terniflora prefers its roots in the shade and its foliage in full sun (Floridata, 2007). C. terniflora can grow in light (sandy), medium (loamy), or heavy (clay) soils as long as the medium is fairly well drained. C. ternifloraalso tolerates a variety of pH, including highly alkaline settings (PFAF, 2004). Because C. terniflora lacks the root hairs or tendrils that most vines use to climb, C. terniflora must either lean and be supported on the trees it overtakes, or grow as a thick groundcover (Kemper, 2007). C. terniflora frequently occurs in hedgerows, forest margins, slopes, supported by rocks near coastal areas, and in disturbed areas (PFAF, 2004).
Reproduction
Clematis terniflora reproduces both vegetatively and by seed. Ripe seeds germinate within 1-9 months. Internodal cuttings are also successful (PFAF, 2007).

General Impacts
Clematis terniflora is used as a landscape ornamental, although its popularity is decreasing as landscapers realize its invasive potential. C. terniflora has the potential to climb 7.6-9.1 metres and smother fully grown trees, or, if necessary support structure is absent, to sprawl along the ground 15-30cm tall and 3 metres wide. Ground cover form of C terniflora will choke out weeds or other plants trying to spring from ground. (Floridata, 2007)
