Any of the more than 325 species of perennial, chiefly climbing shrubs of the genus Clematis (buttercup family), found through most of the world, especially in Asia and North America. Many species are cultivated in North America for their attractive flowers, either solitary or in large clusters. The leaves usually are compound. Common species include woodbine; traveler's joy, or old-man's-beard (C. vitalba); virgin's bower (C. cirrhosa); and vine bower (C. viticella). The most popular horticultural hybrids are of primarily three species: C. florida, C. patens, and C. jackmanii.

clematis (klĕm'ətĭs, kləmăt'ĭs), any plant of the large genus Clematis (sometimes subdivided into three or four genera), widely distributed herbs or vines of the family Ranunculaceae (buttercup family), many of them native to the United States. Some have an irritating sap. The vines, climbing by tendrils that are modified leafstalks, are the more popular and are usually profuse bloomers. The flowers are varied in shape and color; the fruits are small and dry, with a feathery appearance. Most popular in North America are the Jackman clematis (C. jackmanii), a large purple hybrid, and the Japanese clematis (C. paniculata) with small white flowers. Some clematises are called virgin's-bower, traveler's-joy, leatherflower, and old-man's-beard. Clematis is classified in the division Magnoliophyta, class Magnoliopsida, order Ranunculales, family Ranunculaceae.

Clematis is a genus of climbing vines with showy flowers. They are popular among gardeners, and over 200 species are known[1] with more cultivars being produced constantly. Most species are known as clematis in English, while some are also known as traveller's joy, old man's beard, leather flower, vase vine and virgin's bower, the last three being names used for North American species.

Etymology

The genus name is pronounced /ˈklɛmətɨs/,[2] from Ancient Greek klématis, a climbing plant, probably periwinkle. There are over two hundred species and cultivars, often named for their originators or particular characteristics.

Botany

The genus is composed of mostly vigorous, woody, climbing vines technically called lianas. The woody stems are quite fragile until several years old.[1] Leaves are usually divided into leaflets, with leafstalks that twist and curl around supporting structures to anchor the plant as it climbs.[1] Some species are shrubby, and some others are herbaceous perennial plants. The cool temperate species are deciduous, but many of the warmer climate species are evergreen. They grow best when their roots are shaded but their tops are in full sun. They are generally acid-intolerant calciphytes that grow on limestone and other basic soils.

Though they are famous as flowering plants, the clustered true flowers are in fact tiny; the showy parts are actually sepals that resemble colorful flower petals.[1] The blossoms and sepals eventually fall away leaving fluffy clusters of seeds with tails.[1] The timing and location of flowers varies; spring-blooming clematis flower on the previous year's stems, summer/fall blooming clematis bloom only on the ends of new stems, and twice-flowering clematis do both at the respective times.[1]

Clematis species are found throughout the temperate regions of both hemispheres, and also in mountains in the tropics. Clematis leaves are food for the caterpillars of some Lepidoptera species, including the Willow Beauty (Peribatodes rhomboidaria).

Use and toxicity

Clematis was called pepper vine by early travelers and pioneers of the American Old West and used as a pepper substitute to spice up food since true black pepper (Piper nigrum) was a costly and rarely obtainable spice. The entire genus contains essential oils and compounds which are extremely irritating to the skin and mucous membranes. Unlike black pepper or Capsicum, however, the compounds in clematis cause internal bleeding of the digestive tract if ingested in large amounts. The plants are essentially toxic. Despite its toxicity, Native Americans used very small amounts of clematis as an effective treatment for migraine headaches and nervous disorders. It was also used as an effective treatment of skin infections.[3]

Subdivisions

One recent classification recognised 297 species of clematis, so it is not surprising that taxonomists and gardeners subdivide the genus. Several classification systems exist.

Magnus Johnson divided Clematis into 19 sections, several with subsections.[4] Christopher Grey-Wilson divided the genus into 9 subgenera (Clematis, Cheiropsis, Flammula, Archiclematis, Campanella, Atragene, Tubulosae, Pseudanemone, Viorna), several with sections and subsections within them.[5] Several of the subdivisions are fairly consistent between these two systems; for example, all of Grey-Wilson's subgenera are used as sections by Johnson. Alternatively, John Howell defined twelve groups: the Evergreen, Alpina, Macropetala, Montana, Rockery, Early Large-Flowered, Late Large-Flowered, Herbaceous, Viticella, Texensis, Orientalis, and Late Mixed groups.[6]

Many of the most popular garden forms are cultivars belonging to the Viticella section of the subgenus Flammula as defined by Grey-Wilson. These larger-flowered cultivars are often used within garden designs to climb archways, pergolas, wall-mounted trellis or to grow through companion plants. These forms normally have large 12-15cm diameter upward-facing flowers and are believed to involve crosses of C. patens, C. lanuginosa and C. viticella.[7] Early-season, large-flowering forms (eg. "Nelly Moser") tend towards the natural flowering habit of C. patens or C. lanuginosa while later-flowering forms (eg. x jackmanii) are nearer in habit to C. viticella.
