Rhizomatous perennial herb. Leaves are sessile, < 15 x 5 cm and oblong, with prickles < 1 cm long. Flowers are red/pink/purple and borne in December – February. Achenes have white pappus attached.
To help protect our environment, from 1 September 2021, you:
Pasture, roadsides, riparian margins, open coastal areas.
Seeds dispersed by wind. Vegetative spread from rhizomes. Human-mediated dispersal through contamination of machinery.
Infests pasture, reducing milk and animal yields due to herbivore avoidance. Spines injure livestock’s mouths, promoting ‘scabby mouth disease’. Seed heads contaminate wool.
Maintaining good pasture cover can prevent establishment or suppress an infestation. Mowing before flowering will reduce spread of seeds.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
