Japanese knotweed is a highly invasive perennial weed which can cause severe damage to both residential and commercial property and is considered controlled waste. Anyone who has been affected by Japanese Knotweed knows how difficult it is to deal with. Large sums of money are being spent in the United Kingdom controlling the weed. In 2004, a DEFRA review of non-native species policy stated that an estimate for the costs involved in eradication would be £1.56bn.

One of the features that the plant is most easily identified by its heart shape leaves, which are green and flat with pronounced mid-ribs and veins. In spring red or purple shoots appear from the ground and grow very quickly forming long canes. As the canes grow the leaves gradually unwind and turn green in colour and has a creamy white flower.
