Clematis is a genus of over 250 species, most of which are woody to semi-woody deciduous vines climbing by twining leaf stalks or in some cases trailing over support, but in a few cases grow as freestanding or sprawling herbaceous perennials and small deciduous or evergreen shrubs. Most have flat, cupped or bell-shaped flowers. Some plants feature ornamental fluffy seed heads in autumn. Plants bear opposite, simple to compound leaves which are usually deciduous but sometimes evergreen. Compound leaves range from lobed to trifoliate to biternate to pinnate to bipinnate. Clematis is native to both the Northern and Southern Hemispheres including Europe, the Himalayas, China, Australia, North America, and Central America.
