Nto to be confused with : Knotgrasses [plants from the same Family but with similar names]

Some similarities to : Himalayan Knotweed, but there the flowers are white not pink, and the veins on the leaves are much more pronounced red and generally wider.

Lesser Knotweed is a perennial.

Not to be confused semantically with : Knotgrasses, which although they belong to the same Dock & Knotweed Family, belong to a differing Species, namely Polygonium [they both have similar names]. Nor with Knapweeds such as Common Knapweed mor Greater Knapweed.
