P. quinquefolia is a woody, deciduous vine widely cultivated as an ornamental that has escaped from gardens to become naturalized and invasive in natural habitats. It is a fast-growing plant that climbs to a height of 15-20 m on trees, poles or other structures. The tendrils of this vine end in small adhesive pads which stick firmly to stone or bark. This vigorous vine grows forming dense blankets of foliage that shading-out herbs, shrubs, and trees in the canopy and understory. Currently it is regarded as an environmental weed in Australia and it is listed as invasive in several countries in Europe, China and in Cuba (Oviedo and Gonzalez-Oliva, 2015;DAISIE, 2017;Flora of China Editorial Committee, 2017;GRIIS, 2017;Weeds of Australia, 2017). Within the UK it is listed as an invasive non-native species on Schedule 9 in the UK Wildlife and Countryside Act.
