Japanese knotweed is a pioneer species that is believed to have its origins in the volcanic mountains of Japan some 150 million years ago. Its ability to survive in hostile conditions at high altitude, helped it to gradually spread across what is recognised as its native territory of Japan, Korea, Taiwan and parts of China.
Japanese knotweed, a highly invasive plant species, has undergone multiple reclassifications since it was first identified. Initially placed in the Polygonum genus, it has moved through various taxonomic stages, being categorised under Fallopia and, most recently, Reynoutria. Understanding its biology and behaviour is crucial for managing and controlling its spread, preventing further ecological and economic damage.
Foraging, the gathering of wild food for free from its natural habitat, was once the domain of upmarket chefs, but since the pandemic it’s hit the mainstream
