Perennial herb <60cm high. Narrow, greeny-purple leaves with distinctive deep red-purple sheathes. Greenish-cream, sometimes purple-striped flowers (Dec) form loose cluster on long spikes. Numerous small cormils.
Roadsides, waste areas, drains.
Cormils spread via fill material, roading machinery, water in drains & waterways.
Out-competes native species.
Not shade tolerant; good cover of vegetation will inhibit reinfestation. Treatment before flowering reduces cormil production
1. Grub out scattered plants removing all cormils.
2. Weed wipe summer (500ml glyphosate/4L).
3. Spray spring - early summer (100ml glyphosate + 20ml penetrant/10L or 5g metsulfuron + 10ml penetrant/10L)
