| Reynoutria japonica, synonyms Fallopia japonica and Polygonum cuspidatum, is a species of herbaceous perennial plant in the knotweed and buckwheat family Polygonaceae.[1][2] Common names include Japanese knotweed[2] and Asian knotweed.[3] It is native to East Asia in Japan, China and Korea. In North America and Europe, the species has successfully established itself in numerous habitats, and is classified as a pest and invasive species in several countries.[2][4][5] The plant is popular with beekeepers, and its young stems are edible, making it an increasingly popular foraged vegetable with a flavour described as lemony rhubarb.[6] |
