Japanese Knotweed is an herbaceous perennial plant that first came from Asia to Europe in the mid-19th century as an ornamental plant. Amazingly japanese knotweed is infertile, and spreads purely from the disturbance and movement of its rhizome system; rhizome is an underground stem that roots and shoots develop from. A tiny fragment japanese knotweed rhizome, as small 0.4g, is enough to spread the infestation elsewhere.

Knotweed can grow up to 10cm a day = 70cm a week = 2.8metres a month!
