Clematis
Clematis is a genus of about 380 species within the buttercup family, Ranunculaceae. Their garden hybrids and cultivars have been popular among gardeners, beginning with Clematis 'Jackmanii', a garden staple since 1862. More cultivars are being produced constantly, mainly of Chinese and Japanese origin.
Most species are known as clematis in English, while some are also known as:
The genus name Clematis is from Ancient Greek κληματίς : clēmatís, ("a climbing plant") from κλήμα : klḗma – 'twig, sprout, tendril'.
The genus is composed of mostly vigorous, woody, climbing vines / lianas. The woody stems are quite fragile until several years old. Leaves are opposite and divided into leaflets and leafstalks that twist and curl around supporting structures to anchor the plant as it climbs. Some species are shrubby, while others, like C. recta, are herbaceous perennial plants. The cool temperate species are deciduous, but many of the warmer climate species are evergreen. They grow best in cool, moist, well-drained soil in full sun.
Clematis species are mainly found throughout the temperate regions of the Northern Hemisphere, rarely in the tropics. Clematis leaves are food for the caterpillars of some Lepidoptera species, including the willow beauty (Peribatodes rhomboidaria).
The timing and location of flowers varies; spring-blooming clematis flower on side shoots of the previous year's stems, summer/fall blooming clematis bloom only on the ends of new stems, and twice-flowering clematis do both.
The genus Clematis was first published by Carl Linnaeus in Species Plantarum in 1753, the first species listed being Clematis viticella. The genus name long pre-dates Linnaeus. It was used in Classical Greek for various climbing plants, and is based on κλήμα (klēma), meaning vine or tendril.
Some morphologically distinctive taxa lacking the combination of characters defining Clematis were formerly segregated as the genera Archiclematis (1 species) and Naravelia (several species). DNA sequence studies have found that these two genera are deeply nested in Clematis, the morphological characters they were erected on being either reversals or misinterpretations, and that consequently the genera should be reduced to the synonymy of Clematis. Naravelia is a monophyletic group within Clematis.
