What you need to know

To help protect our environment:

  • You must not breed, distribute, release or sell ferny asparagus. As ferny asparagus is a National Pest Plant Accord species, these restrictions apply within the Auckland region and across the whole of New Zealand.
  • You must not plant ferny asparagus 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 ferny asparagus 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.


Forest, shrubland, coastal cliffs, dunes, hedgerows, gardens.


Seeds probably dispersed by birds. Human-mediated dispersal through dumping of garden waste and deliberate planting.

Impact on environment

Potential to smother native vegetation, reducing regeneration and causing canopy collapse. May alter invertebrate communities.


Site Management

Cut and pull vines away from desirable trees and native plants before foliar spraying. 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.

Recommended approaches

Physical control

Method: Dig out.

Plant parts requiring disposal: Tubers, rhizomes and seeds.

Disposal options: Rot tubers, rhizomes and seeds in covered water barrel or remove to greenwaste or landfill.


Biocontrol is currently not available for this species.

Community agrichemical control recommendations

No qualifications: Foliar spray with 200ml glyphosate green per 10L of water.

Certified Handler/Experienced agrichemical user: Foliar spray with 200ml glyphosate green per 10L of water and 10ml penetrant.
