Clump-forming perennial grass < 2 m tall. Roots are deep and fibrous. Stems are erect, purple/white and covered in fine hairs. Leaves are light green with darker green underside, strongly ribbed and tough. Flowerhead is narrow, cylindrical and spike-like.
To help protect our environment:
Pastures, roadsides, streambanks, swamps, wasteland, urban areas, cemeteries, gardens.
Seeds dispersed by wind, water and attachment to animal pelts. Vegetative spread from rhizome fragments.
Aggressive invader. Particularly threatens native species in grassland, scrubland, wetland and sand-dune habitats. Dense clumps may restrict access to natural areas.
Unpalatable to livestock, do not graze. Do not treat when seed mature as increases contamination risk. Fire hazard after spraying. Follow-up spray at least 6 monthly until regrowth ceases. Do not replant with monocots for 2 years after initial spray. Where possible replant with dicot groundcover spp. to allow follow-up haloxyfop spraying.
Do not attempt to undertake control of this species. Please report to Auckland Council.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
