Themeda triandra is a species of C4 perennial tussock-forming grass widespread in Africa, Australia, Asia and the Pacific. In Australia it is commonly known as kangaroo grass and in East Africa and South Africa it is known as red grass and red oat grass or as rooigras in Afrikaans. Kangaroo grass was formerly thought to be one of two species, and was named Themeda australis.
The plant has traditional uses as food and medicine in Africa and Australia. Indigenous Australians harvested it to make bread and string for fishing nets around 30,000 years ago. It was used as livestock feed in early colonial Australia, but this use was largely replaced by introduced plants. As of 2021 there is a large government-funded project underway to investigate the possibility of growing kangaroo grass commercially in Australia for use as a regular food source for humans.
