| Japanese Knotweed (Fallopia japonica) was introduced from the far east to the UK in the 1850s as an ornamental and fodder plant. It is a clump forming perennial weed typically found growing on derelict wasteland and areas of disturbed soil. The plant can grow up to 3 metres in height with an extemely vigorous root system and may cause structural damage. It can penetrate hard surfaces such as tarmac and has been known to penetrate through the foundations of houses. Once present at a site Japanese knotweed spreads very rapidly forming monoculture stands. |  |
