Polygonum arenastrum, commonly known as equal-leaved knotgrass,[2] is a summer annual flowering plant in the knotweed family Polygonaceae. Other common names include common knotweed, prostrate knotweed, mat grass, oval-leaf knotweed,[3] stone grass, wiregrass, and door weed, as well as many others. It is native to Europe[4] and can be found on other continents as an introduced species and a common noxious weed. Knotweed was first seen in North America in 1809 and is now seen across much of the United States and Canada.
