Clematis is a genus of about 380 species [2] [3] within the buttercup family, Ranunculaceae. [4] Their garden hybrids and cultivars have been popular among gardeners, [5] beginning with Clematis 'Jackmanii', a garden staple since 1862; more cultivars are being produced constantly.
Clematis armandii (also called Armand clematis or evergreen clematis) is a flowering climbing plant of the genus Clematis. Like many members of that genus, it is prized by gardeners for its showy flowers. It is native to much of China (except the north and extreme south) and northern Burma. [1] The plant is a woody perennial.
Clematis paniculata is an evergreen woody high-climbing vine. [5] [6] It has a woody stem that is usually around 10 cm or more in diameter at the base. The leaves are dark and globous, sparsely hairy beneath. They have stout branchlets. [7] They have a leaf margin of toothed, entire or lobed near apex, though they are rarely ever profoundly ...
The following species in the flowering plant genus Clematis are accepted by Plants of the World Online. [1] Although the genus is currently most diverse in warm temperate regions and mountainous habitats, molecular evidence suggests that this is of recent origin, and earlier diversification occurred in more tropical climes.
The leaves are opposite and pinnately compound, trifoliate (3 leaflets) that have coarse unequal teeth on the margins. It produces small dull white flowers of width 13 to 19 mm ( 1 ⁄ 2 to 3 ⁄ 4 in) from July to September that are faintly sweetly fragrant; sometimes dioecious so that there are separate staminate (male) and pistillate (female ...
The origin of the genus Clematis comes from the Greek term klematis, which was a word for a climbing and vining plant. The root word Klema means a broken branch or twig, likely used for grafting. Klema stems from the word Klan, meaning to break. [8] The origin of the species name terniflora is Latin for flowers in three.
Calophoma clematidina is a fungal plant pathogen and the most common cause of the disease clematis wilt affecting large-flowered varieties of Clematis.Symptoms of infection include leaf spotting, wilting of leaves, stems or the whole plant and internal blackening of the stem, often at soil level.
The leaves range from 2 to 12 centimeters (0.79 to 4.72 in) in length and 1 to 5 centimeters (0.39 to 1.97 in) in breadth (occasionally as wide as 6 centimeters (2.4 in). They lack conspicuous netted veins, and bear a sparse to dense coating of long short hairs on the underside.
