Flowers unscented, weakly distichous; perianth tube obliquely funnel-shaped, 10–12 mm; tepals pink to light purple with narrow median white streak on outer 3 tepals, unequal, dorsal tepal 45–50 × ca. 16 mm, inner lateral tepals ca. 30 × 8 mm, outer 3 tepals connate for ca. 5 mm, outer lateral tepals ca. 25 mm, outer median tepal ca. 20 mm; filaments ca. 12 mm; anthers ca. 15 mm; style branching opposite level of anther apices; branches ca. 2.5 mm.

Gladiolus italicus is a weed of cultivation, not known certainly as a truly wild plant. Occasionally, small-flowered plants with aborted anthers occur in some populations, but such gynodioecious individuals have not been recorded in North America.
