Bushy, much-branched, thistle-like biennial forb < 1.5m tall. Leaves are < 50 cm long. Flowers are spiky green spheres with pink/purple centres and bracts that become hooked when dry, and are borne January – April. Seeds are attached to pappus.
To help protect our environment:
Forest margins, scrub, creek beds, pasture, gardens, wasteland, open and disturbed sites.
Seeds dispersed by wind, water, attachment to animals and humans.
Burs contaminate sheep wool and injure livestock. Taints milk if foraged in large quantities. Reservoir for fungal diseases that could impact horticultural plants. Can cause contact dermatitis and toxic seed hairs may be irritating to pets and humans.
Maintaining good pasture cover will suppress an infestation. Mowing before flowering will reduce spread of burs. Control is most effective on first year rosettes.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
