原生地・分布（英語）: Europe, Medit., Asia

説明（英語）: Genus of 15 species of perennials found in scrub, woodland, and grassy and rocky sites, usually on chalk or lime-stone soils, from C., E., and S. Europe to W. Asia. They are rhizomatous, and either clump-forming with deciduous, basal leaves or almost shrub-like, with leafy, biennial stems. The leaves are lobed or fully divided into leaflets, and often pedate (the lateral leaflets or lobes further subdivided or lobed); they are generally toothed, leathery, and light to dark green. The loose, usually few-flowered cymes, to 45cm (18in) tall in most species, have leafy bracts and are borne from late winter to mid-spring. The flowers are white, cream, pink, purple, or green, sometimes spotted, and are pendent or outward-facing, saucer-to cup-shaped, or tubular-bell-shaped. Each has 5 tepals, numerous stamens, and 2-10 free carpels. Hellebores are effective when grown in groups in a mixed or shrub border, or naturalized in a woodland garden. Smaller species are ideal for a rock garden. All parts may cause severe discomfort if ingested, and the sap may irritate skin on contact.

耐寒性（英語）: Fully hardy to frost hardy.

栽培（英語）:

繁殖（英語）: Sow seed in containers in a cold frame as soon as ripe; named cultivars do not come true from seed. Divide all species and named cultivars after flowering, in early spring or late summer. H. foetidus and H. argutifolius are best raised from seed as they are not suitable for division.

病害虫（英語）: Susceptible to snails, aphids, leaf spot, and black rot.
