WClematis is a genus of about 300 species within the buttercup family, Ranunculaceae. Their garden hybrids have been popular among gardeners, beginning with Clematis × jackmanii, a garden standby since 1862; more hybrid cultivars are being produced constantly. They are mainly of Chinese and Japanese origin. Most species are known as clematis in English, while some are also known as traveller's joy, a name invented for the sole British native, C. vitalba, by the herbalist John Gerard; virgin's bower for C. terniflora, C. virginiana, and C. viticella; old man's beard, applied to several with prominent seedheads; leather flower for those with fleshy petals; or vase vine for the North American Clematis viorna.
WOld man's beard is an invasive plant in New Zealand that affects indigenous biodiversity. It is declared an unwanted organism under the Biosecurity Act 1993 which means it cannot be sold, distributed or propagated.
WClematis akebioides is a plant that originates in Western China. It is a flowering plant that comes in many different colors. It is mainly greenish yellow in color. It contains certain chemical constituents that are widely used in western medicine. The plant is a photoautotroph, meaning it transforms light energy received from the sun into chemical energy through photosynthesis. This species is unique from others from its genus in that it emits a sweet smell. The species usually grows in shrub lands where it uses its stems to provide support for other plants.
WClematis alpina, the Alpine clematis, is a flowering deciduous vine of the genus Clematis. Like many members of that genus, it is prized by gardeners for its showy flowers. It bears 1 to 3-inch spring flowers on long stalks in a wide variety of colors. C. alpina is native to Europe; in the United States it grows best in American Horticultural Society zones 9 to 6, which are generally found in the southern USA.
WClematis aristata, known as Australian clematis, wild clematis, goat's beard or old man's beard, is a climbing shrub of the family Ranunculaceae, found in eastern Australia in dry and wet forests of Queensland, New South Wales, Victoria and Tasmania. In spring to early summer it produces mass displays of attractive star-shaped flowers usually borne in short panicles with each flower up to 70 mm diameter and possessing four narrow white or cream tepals. Fertile male and female reproductive structures occur in flowers of separate plants (dioecy) making this species an obligate outcrosser with pollen movement among plants most likely facilitated by insects. Each seed head on female plants consists of multiple achenes with each seed bearing a plumose awn 2–4.5 cm long promoting dispersal by wind.

WDelphinine is a toxic diterpenoid alkaloid found in plants from the Delphinium (larkspur) and Atragene genera, both in the family Ranunculaceae. Delphinine is the principal alkaloid found in Delphinium staphisagria seeds – at one time, under the name stavesacre, a very well known herbal treatment for body lice. It is related in structure and has similar effects to aconitine, acting as an allosteric modulator of voltage gated sodium channels, and producing low blood pressure, slowed heart rate and abnormal heart rhythms. These effects make it highly poisonous, but in very small doses it has some uses in herbal medicine.
WClematis drummondii is a species of flowering plant in the buttercup family, Ranunculaceae, that is native to the Southwestern United States and northern Mexico. Common names include old man's beard, Texas virgin's bower, and barba de chivato. It is a white-flowered vine that can be found clambering among other wildflowers, on shrubs and on fence rows. The natural habitat of C. drummondii includes the Chihuahuan and Sonoran deserts as well as prairies and grasslands. The sap of this plant is caustic, although its foliage, stems, and roots can be used for dye if caution is used while handling and if breathing the fumes is avoided.
WClematis flammula is a temperate liana known by the common name fragrant virgin's bower.

WOver 70 species and cultivars of clematis currently (2016) possess the Royal Horticultural Society's Award of Garden Merit, reflecting this plant's continued popularity in gardens in the United Kingdom. Clematis is a genus of woody based perennials, mostly climbers with a twining habit, though some are grown as groundcover or as herbaceous plants. They can be evergreen or deciduous. They bear flowers in all shades except black, pure blue, pure red and orange. The flowers are often large and showy. They can be single or double, fragrant or unscented, compact or vigorous, in a wide range of shapes and sizes. The flowering period varies from early spring to late summer. Many spring-flowering cultivars produce a second flush of blooms after the main display has finished, and many have attractive silky seed-heads prolonging the period of interest. Clematis can be grown against walls, fences, over pergolas and obelisks, or through other shrubs and trees.
