Asiatic tearthumb

Persicaria perfoliata

Overview

  The Asiatic tearthumb – sometimes referred to as the mile-a minute plant – is a fast growing herbaceous vine native to Asia. It is usually found in open areas along the edges of woods, wetlands, riverbanks, roadsides, and uncultivated fields where it scrambles over shrubs and other vegetation, blocking out the light, and eventually suffocating all that lies beneath. Large infestations can reduce the biodiversity of natural habitats, resulting in the local extinction of rare native plants with restricted ranges. It can also cause economic losses to orchards, nurseries, and horticultural crops. Although not yet established in the EU, the plant is already a major pest in other parts of the world, such as the US. Concerted action at EU level will prevent the species from being introduced to Europe by addressing its introduction pathways, such as inter alia contaminated soil, plant or seed imports, and by rapidly eradicating any emerging invasion.
