原生地・分布（英語）:

説明（英語）: Genus of about 45 species of annuals, biennials, and deciduous or evergreen, often short-lived or monocarpic perennials. They occur in moist, shady mountainous areas, alpine meadows, woodland, scrub, scree, and rocky slopes in the Himalayas, Burma, and China, with one species from W. Europe. Usually hairy or bristly, they produce basal rosettes of pinnate or simple leaves, which may be entire, toothed, lobed, or pinnatisect. The lower leaves are long-stalked, the upper ones short-stalked or stalkless. The flowering stems, usually one per leaf rosette, are either leafless and unbranched, each bearing a solitary flower, or leafy and branched near the top, bearing flowers singly or in short racemes or panicles, the uppermost opening first. The flowers are generally pendent, saucer- to cup-shaped, poppy-like, and silky, with numerous stamens and usually 4, but sometimes up to 9 petals. The flower-stalks lengthen after flowering as the fruits develop. Meconopsis species grow best in areas with cool, damp summers. Most are suitable for growing in large groups in a moist, cool woodland garden, but also perform well in a moist peat bed or terrace. M. cambrica is suitable for a wildflower garden but will thrive almost anywhere, except in very dry soils.

耐寒性（英語）: Fully hardy; young growth may be damaged by late frosts.

栽培（英語）:

繁殖（英語）: Sow seed in containers in a cold frame, preferably as soon as ripe or in spring. Use loamless seed compost, sow thinly, and keep moist; light is needed for germination. Over winter, keep young plants produced from autumn sowings in a cold greenhouse or frame. Seedlings are prone to damping off. Divide after flowering. Root vegetative buds of M. chelidoniifolia when they appear in the upper leaf axils.

病害虫（英語）: Susceptible to downy mildew and to damage caused by slugs and snails.
