原生地・分布（英語）:

説明（英語）: Genus of 2 species of herbaceous perennials, with twining stems, widely distributed and naturalized in woodland and hedgerows in N. temperate regions (their exact country of origin is unknown). The cultivars are grown for their brightly coloured foliage, which may be golden or attractively variegated. The leaves are opposite and palmately 3- to 7-lobed, with large, broadly ovate to rounded lobes. Small male and female flowers are borne on separate plants in mid- and late summer; the males in axillary panicles, the females in cone-like spikes. The female inflorescences of H. lupulus ("hops") are used in brewing. Train over a fence or trellis, or into a large shrub or small tree. The flowers are useful for dried flower arrangements.

耐寒性（英語）: Fully hardy to half hardy.

栽培（英語）:

繁殖（英語）: Sow seed at 15-18°C (59-64°F) in spring; seed of H. japonicus and its cultivars may be sown in situ in late spring. Variegated and golden-leaved cultivars other than H. japonicus ’Variegatus’ do not often come true from seed. Root softwood cuttings in spring, or greenwood and leaf-bud cuttings with bottom heat in summer.
