Roscoea tibetica is a perennial herbaceous plant native to the mountains of China, being found in Tibet, Sichuan and Yunnan. The species formerly included plants found in Bhutan; in 2000, these were separated into a new species, Roscoea bhutanica. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but R. tibetica, like other species of Roscoea, grows in much colder mountainous regions. R. tibetica is sometimes grown as an ornamental plant in gardens. In 2020, it was proposed that R. tibetica be split again.
