This plant is quite possibly not hardy in Britain,  gives a hardiness zone of 10, which means that it is not frost tolerant. However  says that it grows in all areas of lowland Japan and this should include areas that do experience frosts and snow. Another report says that many forms of this species are not frost-hardy, though some forms have hardy roots. There is also a lot of confusion over the correct name for this species. Some reports give O. stolonifera. DC. or O. stolonifera. Wall as the correct name whilst other reports say that these names are synonyms of O. javanica.  says that O. stolonifera japonica. (Miq.)Maxim. is a synonym of O. javanica. It is quite possible that both O. javanica and O. stolonifera are valid names and the uses listed here belong partly to each species. More research is required.This species is occasionally cultivated for its edible root or for its edible leaves according to another report, there are some named varieties. There are two main forms of this species, a red form has edible shoots whilst a white form is grown for its medicinal root. In Japan this plant and six other herbs are customarily boiled in rice gruel on January 7th. The cultivar 'Su Zhou' is medium early and has few fibres plus an excellent taste.
