Tritonia gladiolaris is a Tritonia genus in the Iridaceae family from the grasslands of southern-eastern Cape of South Africa. It was is cultivated as a garden ornamental but has escaped and it is now a weed of grasslands, roadsides, waste areas and disturbed sites in some of the warmer areas of New Zealand.
Tritonia gladiolaris an upright herbaceous plant usually growing 30-60 cm tall and re-growing each year from long-lived underground ±2 cm diameter corms.
The long leaves are long and strap-like (>35 cm long and >18 mm wide). They have entire margins, pointed tips and three to five prominent parallel veins. They are sheathed at the base.

The flower styles are divided into three branches and hence they have three stigmas. sweet-smelling, The flowers give off a very strong fragrance, especially at night. They are not grazed by animals.
After flowering oval fruit capsules (3-8 mm long) form, they turn brown and split open when mature releasing many seeds that are spread by wind and water. Tritonia gladiolaris also reproduces vegetatively via its underground corms. Both seeds and corms are spread in contaminated soil and dumped garden waste.

This Tritonia gladiolaris was growing wild on wasteland in New Plymouth, Taranaki.
