Rohdea japonica is a species of plant native to Japan, China and Korea.[2][3][4][5] Common names include Nippon lily, sacred lily, and Japanese sacred lily.

It is a rhizomatous herbaceous perennial plant, with fibrous roots. The leaves are evergreen, broad lanceolate, 15–50 cm long and 2.5–7 cm broad, with an acute apex. The flowers are produced in a short, stout, dense spike 3–4 cm long, each flower pale yellowish, 4–5 mm long. The fruit is a red berry 8 mm diameter, produced in a tight cluster of several together.

Cultivation and uses

It is cultivated as an ornamental plant. In Chinese it is called wan nian qing (simplified: 万年青; 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.
