原生地・分布（英語）: S.Africa, Europe (6), Medit.

説明（英語）: Genus of about 180 species of cormous perennials from rocky slopes, seasonally dry grasslands, and marshy areas, mainly in South Africa, but also from the Mediterranean, the Arabian Peninsula, N.W. and E. Africa, Madagascar, and W. Asia. They are grown for their showy spikes of usually open, funnel-shaped flowers, borne mainly from spring to early autumn. The flowers each have 6 tepals: usually 1 central upper tepal, 3 often quite small lower or lip tepals, and 2 side or wing tepals. They open from the bottom of the spikes upwards, older blooms dying off as new ones develop (the number of buds open at any one time is given in brackets in each hybrid and cultivar description below). Erect leaves, borne in basal fans, are narrow, linear or sword-shaped, mid- to dark green, and 24-60cm (10-24in) long. Plant gladioli in clumps in a mixed border, or in rows for cutting. In frost-prone climates, grow frost-hardy gladioli by a sheltered, sunny wall; winter-flowering South African gladioli require a cool greenhouse. In warmer areas, plant in open, sunny, well-drained sites. Over 10,000 hybrids and cultivars have been developed for garden cultivation, exhibiting, and cutting. They are classified into three main groups: Grandiflorus, Nanus, and Primulinus (see below). Flowers may be borne either in a formal arrangement, side by side on the stem, so when open there is no daylight visible between them, or less formally, with one bloom above another, like a step-ladder.

耐寒性（英語）: Fully hardy to frost tender.

栽培（英語）:

繁殖（英語）: Sow seed of hardy species in containers in a cold frame in spring; sow seed of half-hardy to tender species at 15°C (59°F) in spring. Separate cormlets when dormant.

病害虫（英語）: Prone to gladiolus corm rot, various types of grey mould (Botrytis), thrips, aphids, and slugs.
