It is cultivated as an ornamental plant. In Chinese it is called wan nian qing (simplified: ; traditional: 萬年青; lit. "evergreen"), and for this reason has been used symbolically in visual culture (e.g. on Mao badges Archived 2014-08-13 at the Wayback Machine). In Japanese it is called omoto.

The plant is also used in traditional Chinese medicine, though it is generally regarded as inedible and possibly toxic.
