Identifying Japanese Knotweed - What Japanese Knotweed Looks Like

For the non-specialist, the best time to identify Japanese Knotweed is in late summer, when the plant has flowers. Identification can be difficult in the winter when the plant has died back. Have a look at our photo gallery for help. We have also provided some excellent pdf guides to help with identification. Finally, take a look at the BBC video below which should also help in identification. There are other species of plants which look like knotweed and occasionally turn up in the garden, confusing identification - See further down the page to find out how we can help.
