Gladiolus communis, the eastern gladiolus or common corn-flag, is a species of flowering plant in the family Iridaceae, native to temperate northern Africa, western Asia and southern Europe, from the Mediterranean to the Caucasus, and widely naturalised in frost-free locations elsewhere – such as coastal parts of the southwestern British Isles. It is a vigorous cormous herbaceous perennial growing to 1 m tall with linear leaves and bright pink flowers in spring. Two subspecies are identified: G. communis subsp. communis G. communis subsp. byzantinus (Mill.) A. P. Ham.
