原生地・分布（英語）:

説明（英語）: Genus, closely related to Tigridia, of 4 species of bulbous perennials from dry pine to cloud forest in Central America. They are cultivated for their iris-like, brightly coloured flowers, borne in succession in spring or summer. The long, broadly lance-shaped, many-folded leaves are reduced to short, sharp-pointed, leaf-like bracts on the flowering stems. In frost-prone areas, grow in a cool greenhouse. In warmer areas, grow at the base of a sunny wall or in a warm site where the soil dries out in summer.

耐寒性（英語）: Half hardy, but may withstand short spells at -5°C (23°F).

栽培（英語）:

繁殖（英語）: Sow seed at 13-18°C (55-64°F) in spring.
