Japanese knotweed was first introduced in the UK as an ornamental plant.
The impressive growth and white flowers made it a popular choice for gardeners. Now the World Conservation Union class Japanese knotweed as one of the world's worst invasive species.
Opinions of knotweed have certainly changed over the last 100 years - now everyone wants to eradicate the plant. The question to ask is how this can be done? There are many specialist companies who are tackling it. But can they do it alone, or will they need the support of Government and Local Authority?
