Vines, scramblers or climbing plants can trail or creep along the ground but generally require the support of other plants to grow because their stems, in most cases, lack the central thickening which imparts rigour to trees and shrubs. Their stems are usually supple and can twist and contort in erratic convolutions without affecting the transport of water and nutrients that are essential to their survival.
This category of plants includes some of the most damaging environmental weeds in the Sydney region. It is recommended that all species listed be eradicated from gardens and replaced with less invasive species.
