Stout bamboo grass

Common name: Stout bamboo grass
Botanical name: Austrostipa ramosissima
Management programme: Eradication

Stout bamboo grass originates from south east Australia and was most likely introduced as a garden plant because of its attractive tufted form and long flowering period. It is named due to its bamboo-like appearance.

Why is it a pest?

Stout bamboo grass spreads by seed and reproduces rapidly. It is a problem as it has the potential to colonise moist gully areas and outcompete native vegetation.

Where is it found?

Stout bamboo grass has been found in one localised area in the western Bay of Plenty. It grows best in moist, well-drained gullies, in sheltered positions. It will also grow in exposed dry sites - but not as well.

What does it look like?

  • Stout bamboo grass is an attractive tufted perennial grass, growing 1-2.5m tall.
  • The stems with whorled branches are bamboo-like in appearance.
  • Stout bamboo grass flowers are large and feathery, and long-lasting.

What are the rules?


Eradication pests are present in the region but are limited in their size or extent of infestation. The eradication of these organisms is a feasible and cost-effective solution.  The Bay of Plenty Regional Council is responsible for their control or eradication from the region. Action may be required from landowners or occupiers to support a control operation.

How do you get rid of it?

  1. Spray dense spots (spring - summer).
  2. Spray (all year round).


CAUTION: When using any herbicide or pesticide, PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and directions for the purchase, use and storage of the product, are followed and adhered to.
