Gladiolus oppositiflorus is a robust geophytic herb of summer rainfall grassland in KwaZulu-Natal and the Eastern Cape, also found at the southern end of the Drakensberg Mountains and foothills.
The plants flower pale pink to almost white or deeper shades, as well as mauve or salmon. It grows tall enough for not being missed in the grass. The flowers are from 6,5 cm to 11 cm long.
They are mostly seen near the end of summer (Goldblatt and Manning, 1998; Manning, 2009; Pooley, 1998; iNaturalist).
