The hedge knotweed or hedge knotweed is a species of knotweed (Fallopia) in the knotweed family (Polygonaceae). It occurs in the temperate latitudes of Eurasia and grows on hedges and bushes as well as forest fringes and clearings.
Fallopia dumetorum is an annual herbaceous plant. The usually 60 to 150 centimeters, more rarely up to 3 meters long stem grows creeping and climbing and right-winding; in contrast to the very similar knotweed (Fallopia convolvulus), it is round and smooth. All parts of the plant are bare.
The root is spindle-shaped. The leaves are divided into a petiole and a leaf blade. At the base of the petiole there is a nectar pit. The leaf blade is elongated and pointed and at the base of the blade it is arrow-shaped to heart-shaped with two lateral, triangular or rounded lobes.
