Japanese knotweed is an herbaceous perennial with tubular, glabrous stems that ascend from an erect base. It has hollow stems with distinct raised nodes that give it the appearance of bamboo. While stems may reach a maximum height of 3–4m each growing season, it is typical to see much smaller plants in places where they sprout through cracks in the pavement.

Kikuyu grass is a rhizomatous grass with matted roots and a grass-like or herbaceous habit. It is a prostrate perennial, which may form a loose sward up to 46cm high when ungrazed, but under grazing or mowing, it assumes a dense turf. The grass spreads vigorously from rhizomes and stolons, which root readily at the nodes and are profusely branched.

Knotweed is a mat-like, perennial, herbaceous plant with a slender, woody rootstock and long, creeping, rooting stems. It is found growing on roadsides, dry banks, slopes and in open areas, preferring full sun. It negatively impacts on the environment by forming a dense carpet, replacing most indigenous vegetation.
