Gladiolus (from Latin, the diminutive of gladius, a sword) is a genus of perennial bulbous flowering plants in the iris family (Iridaceae). Sometimes called the sword lily, the most widely-used English common name for these plants is simply gladiolus (plural gladioli, gladioluses or sometimes gladiolas).
The genus is distributed in Mediterranean Europe, Asia, Tropical Africa and South Africa. However, the center of diversity of the genus is located in the Cape Floristic Region, where most species were discovered. As a matter of fact, 163 out of the 250 species of Gladiolus are from Southern Africa.[1] The genera Oenostachys, Homoglossum, Anomalesia and Acidanthera, traditionally considered independent entities, currently are included in Gladiolus.[2]
