原生地・分布（英語）:

説明（英語）: Genus of 6 or more species of cormous perennials from sandy, lowland soils to rocky upland slopes in South Africa. Over 300 cultivars have been developed for use as cut flowers. The large, funnel-shaped, usually scented, brightly coloured flowers, held erect in dense racemes at the end of arching, frequently branched stems, are produced in late winter and early spring. Narrowly sword-shaped to linear-lance-shaped leaves, 5-4Ocm (2-16in) long, develop in basal fans. In frost-prone areas, grow freesias in a cool greenhouse. Specially prepared corms may be used outdoors for summer flowering. In warmer areas, grow in groups in a mixed border.
