The genus name Polygonatum comes from the Greek words "poly", meaning "many", and "gonu", meaning "knee joint". This is in reference to the plant's jointed rhizomes. The Latin specific epithet odoratum means "scented".[5]
Polygonatum odoratum is a colonizing herbaceous perennial growing to 85 cm (33 in) tall by 30 cm (12 in) wide, with alternate, simple leaves on arching stems. The scented tubular flowers are white with green tips, borne in spring and hanging from the underside of the stems.[2]
Polygonatum odoratum, like its relative lily of the valley, is cultivated in moist, shaded situations, where it will spread by underground stolons.[6] Cultivars include 'Flore pleno'[7] and 'Variegatum'.[8]
Polygonatum odoratum is used in traditional Chinese medicine and Traditional Korean medicine, where it is called yùzhú (玉竹) and dunggulle (둥굴레) respectively. In Korea, the root of the plant is used to make tea.
This plant species is described in the work Plantas Medicinales (medicinal plants) of Pius Font i Quer.[9] According to it, its rhizome contains asparagine, mucilage, a cardio-tonic glycoside, saponin, and quinine gluconate. It has been used for intestinal problems and pain, for rheumatism, gout, water retention, and as a diuretic. He says that the scientific medicine has used it to treat diabetes. He also describes a digestive liquor that uses the rhizome of this plant.
The young shoots of the plants may be boiled and served like asparagus. The stems, leaves, and berries, however, must be treated with caution, as they are thought to be toxic if consumed in large quantities.[10]
