Japanese Knotweed Growing Over A Metal Fence

Nice to be notorious

Japanese knotweed was introduced to the UK in the 18th century as an ornamental plant and was widely planted across the UK for its attractive appearance. It’s since then become notorious for rapid growth and causing significant damage to the outer layers and foundations of many homes.

For that reason, it’s become classed as one of the world’s ‘worst species’ of plants by the World Conservation Union.
