What is Japanese Knotweed?
Japanese knotweed identification, first you need to identify the plant – so what is it? Japanese knotweed (Fallopia japonica) and its hybrids are a non-native, invasive species of plant. Since it was introduced into the UK as an ornamental garden plant in the mid-nineteenth century, it has spread across the UK, particularly along watercourses, transport routes and infested waste areas and of course private gardens.
Plants within their native range are usually controlled by a variety of natural pests and diseases. When plants such as this are introduced into new areas, that are free from these pests and diseases, they can become larger and more vigorous. They invade natural habitats and out-compete the native plants and animals that normally live there. Rivers, hedges, roadsides and railways form important corridors for native plants and animals to migrate, and large infestations of non-native weeds can block these routes for wildlife.
