goutweed is a pest in nearly all gardens, and very difficult to get out.
At first you might mistake the Wild Angelica for goutweed, as the leaves are very similar, but there are several differences.
Some of the worst weeds to get out are goutweed and Coltsfoot.
The seeds of the Wild Angelica are quite a different shape from the goutweed seeds.
At the top of each seed-vessel there are two long, thin bristles which bend over, very much like those in the goutweed.
