Japanese knotweed was introduced to the UK from Japan in the 1840s as an ornamental plant, and it is now number one on the list of the UK’s most invasive plant species. The Environment Agency has described it as: ‘Indisputably the UK’s most aggressive, destructive and invasive plant.’

It is particularly rampant along waterways, railways and on many brownfield sites, and its rapid growth – it can grow up to 3m in three months – means that it overshadows native plant species, has a significant impact on wildlife and causes damage to property.
