About

Roscoea cangshanensis was described in 2007 as a perennial herbaceous plant native to the mountains of China, being found in Yunnan. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but R. cangshanensis, like other species of Roscoea, grows in much colder mountainous regions. As of August 2024, Plants of the World Online does not recognize this species, including it within R. forrestii.

Where it grows

Roscoea cangshanensis has been found only in one location, in the Cang Shan mountains in Yunnan, China, where it occurs at 2,600 metres in damp soil under pines.
