Why it is a pest plant


Identifying Features

Production threat Environmental threat Public threat

Old man’s beard is generally now recognised as the most damaging alien climber in New Zealand. One plant can blanket an area up to 180 square metres. Old man’s beard is a vigorous climber that covers and strangles desirable trees and shrubs, eventually blocking out light and killing them. Native bush is particularly vulnerable and large areas can quickly become dominated by this pest.

A native of Europe, old man’s beard was introduced to New Zealand as an ornamental plant. Since then its spread in the Waikato has been recorded across the region, mainly in the King Country, Taupō and Hamilton. There are scattered sites in the Waikato, Waipa and Hauraki districts.

New infestations can come from garden waste dumped in the countryside. The seeds of established plants spread by wind and water, and stem sections sprout and reroot wherever they touch the ground.
