Tritonia is a genus of perennial flowering plants in the iris family Iridaceae with some 28 species. They are naturally distributed mainly in South Africa and are closely related to the genus Ixia. They are small bulbous plants. The leaves are fan shaped. The flowers are shades of yellow, orange or brown; sweet-smelling, and give off a very strong fragrance, especially at night. They occur in a variety of habitats: grassland in summer rainfall areas, renosterveld, karroid scrub, and fynbos in winter rainfall areas. The genus name is derived from the Latin word triton, meaning “weathervane”, and alludes to the apparently random arrangement of the stamens in some species. They are well suited to pot culture.

Tritonia karooica is a perennial flowering plant endemic to the Northern and the Western Cape provinces of South Africa where it can be found growing in the dry stony clay flats of the Roggeveld and the Karoo. Tritonia karooica is a winter-growing, summer-dormant species. For this reason, plant the seeds or corms in autumn between late March and early June. Tritonia karooica is recommended for cultivation in both gardens and containers.
