Burdock

In the UK, two types of burdock, Greater burdock (Arctium minus) and Lesser burdock (Arctium lappa) may be found on waste ground, verges, and hedgerows. The picture shows Greater Burdock. It is a large plant with big leaves. Although the plant is not poisonous, the seed heads can cause problems as they are large and stick strongly to clothes and animal fur.
