Japanese knotweed is a pretty harmful invasive species that is found across the UK, particularly in South Wales and North West England.
Japanese knotweed is one of the most infamous invasive species in the UK, regulated by laws such as the Wildlife and Countryside Act 1981 in an attempt to stop it from spreading further than it already has.
Because knotweed is such a widely condemned plant, you could be forgiven for assuming that it’s highly toxic – why else would people be so afraid of finding it growing on their property?
