原生地・分布（英語）:

説明（英語）: Genus of about 80 species of bulbous perennials found in Central and South America, in habitats ranging from streambanks to rocky hillsides, from sea level to subalpine regions. Umbels of showy, funnel-shaped flowers are borne on leafless stems, mainly from winter to spring. Semi-erect, strap-shaped, Iight to mid-green or grey-green, basal leaves develop with or just after the flowers. Many large-flowered, colourful hybrids (incorrectly known as Amaryllis, a separate South African genus), have been bred for cultivation in containers. These usually produce 4-6 bold, open funnel-shaped flowers, 10-15cm (4-6in) across, and strap-shaped, deep green leaves, 45cm (18in) long. In frost-prone areas, grow as houseplants or in a warm greenhouse or conservatory. In warmer areas, grow in a border or in containers outdoors. All parts may cause mild stomach upset if ingested.

耐寒性（英語）: Mainly frost tender; H. x acramannii may survive short spells outdoors at 0°C (32°F).

栽培（英語）:

繁殖（英語）: Sow seed at 16-18°C (61-64°F) as soon as ripe; keep seedlings growing without a dormant period to encourage early flowering. Remove offsets in autumn.

病害虫（英語）: Susceptible to bulb scale mite, large narcissus bulb fly, and various fungal diseases.
