Perennial mat-forming herb. Rhizomes are creeping. Leaves are basal, simple, deeply lobed and toothed, with a < 20 cm diameter. Flowers are yellow and borne in inflorescence < 30 cm tall, before leaves appear in spring. Achenes are winged.
To help protect our environment:
Riverbeds, riparian margins, ditches, wetlands, gravel, roadsides, crops, open and disturbed habitats.
Seeds dispersed by wind. Vegetative spread from rhizome fragments. Human-mediated dispersal through movement of contaminated machinery and soil.
Forms mats and may outcompete other plants in moist habitats. Competes with pasture grasses and potentially crop plants. Can be toxic to livestock and humans.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
