First, what is Japanese knotweed?

Japanese knotweed’s scientific name is Reynoutria japonica syn. Fallopia japonica & Polygonum cuspidatum and is a non-native, invasive plant that was imported to the UK in the 1800s, from Japan. Originally merited for its beauty, durability, and regenerative powers, it is now widely recognised as a pest species that dominates native plants and causes damage in the built environment.

Why is it called Japanese knotweed?

Japanese: obviously refers to where the plant originates from (despite Taiwan and northern China also being considered home countries).

Knotweed: is composed of knot (Old English cnotta “intertwining of ropes, cords, etc.,” and weed “plant not valued for use or beauty,” Old English weod, uueod “grass, herb, weed of unknown origin, and also applied to trees that grow abundantly.
