説明（英語）: Genus of more than 200 species of evergreen or deciduous, mainly semi-woody to woody, twining leaf-climbers and woody-based herbaceous perennials from the N. and S. hemispheres, including Europe, the Himalayas, China, Australasia, North America, and Central America. More than 400 mainly large-flowered cultivars are in cultivation. Due to the diversity of the species - which include short-growing herbaceous perennials, scandent or trailing shrubs, and climbers reaching 10-15m (30-50ft) in height - habit and leaf form vary greatly. The opposite, occasionally alternate, hairy to hairless leaves are simple, 3-palmate, or pinnate or 2-pinnate, with entire to irregularly cut margins. Climbing species attach to host plants or supporting structures by means of their leaf-stalks. More specific leaf information is given in the group descriptions below. The mostly bisexual, rarely unisexual flowers are borne singly or in cymes or panicles. They have 4-10 sepals (often referred to as petals) and vary greatly in shape and size (see panel below). Clematis are grown for their abundant flowers, often followed by decorative, filamentous, silvery grey seed heads. Some, such as C. recta, are scented. Use climbing species to clothe a wall, arbour, trellis, or pergola; they can also be grown over large shrubs or small trees. Grow herbaceous species in a mixed or herbaceous border. For ease of reference, clematis may be divided into the following 3 groups, based on their cultivation requirements: ardy. Herbaceous species and cultivars - bear flowers on the current year’s shoots from midsummer to late autumn. They are suitable for a mixed border with perennials. The leaves are mid- to dark green or greyish green, either simple and lance-shaped to ovate or heart-shaped, 2.5-15cm (1-6in) long, some with toothed margins, or 2.5-8cm (1-3in) long with 3-5 lance-shaped to ovate leaflets. Single flowers are either saucer-shaped, 1-2cm (1/2-3/4in) across, or bell-shaped or tubular, 1-4cm (1/2-1 1/2in) long. Fully hardy to frost hardy.

耐寒性（英語）: Fully hardy to half hardy. See also group descriptions above.

栽培（英語）:

繁殖（英語）: Sow seed of species as soon as ripe in containers in a cold frame. Divide or take basal cuttings of herbaceous species in spring. Root soft-wood cuttings in spring, or semi-ripe cuttings in early summer. Layer in late winter or early spring.

病害虫（英語）: Clematis wilt may be a problem. Cutworms and voles may cut young stems. Aphids may attack young plants. Whiteflies may be a problem under glass.
