What is Japanese Knotweed?

Japanese Knotweed was introduced into Britain in the 19th century as an ornamental plant. Over time it has become widespread in a range of habitats including roadsides, railway embankments, riverbanks and derelict buildings. The invasive root system and strong growth can out-compete native plants and animals, damage foundations, buildings, roads, paths, retaining walls and architectural sites. It can also reduce the capacity of channels in flood defenses to carry water.
