What you need to know

To help protect our environment:

  • You must not breed, distribute, release or sell buddleia within the Auckland region.
  • You must not plant buddleia within the Auckland region, unless you are transferring an existing plant on your land to another location within the boundaries of the same property.
  • You must destroy any buddleia on land that you occupy if it has been planted in breach of the above rules and you are directed to do so by an authorised person.

Disturbed habitats, riparian and forest margins, riverbeds, landslides, cliffs, regenerating forest, plantations, roadsides, wasteland.

Seeds dispersed by wind and water. Vegetative spread from suckering. Human-mediated dispersal through dumping of garden waste and deliberate plantings.

Forms dense thickets, displaces co-occurring species and alters vegetation composition and succession.

Site Management

Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
