Persicaria barbata, commonly known as bearded knotweed, is a species of flowering plant in the family Polygonaceae.[3][4][5] It is native to the Arabian Peninsula and much of tropical and subtropical Asia, and has also been introduced to parts of Africa and the Pacific islands.[2] The plant typically grows in seasonally dry tropical regions, where it occurs as an erect or sometimes prostrate annual herb, 30–60 cm tall, with hairless, line-grooved stems and lance-shaped leaves up to 15 cm long.[6] In some descriptions it is noted as a perennial, producing robust, loosely branched stems 40–90 cm tall from a creeping rhizomatous rootstock.[7]
