Perennial, rhizomatous herb < 2 m tall. Stems and leaves are hairy with hollow stinging hairs. Leaves are soft, green, < 15 cm long and strongly serrated. Flowers are white/green and borne in dense axillary inflorescences during summer.
To help protect our environment:
Moist soils, disturbed habitats, riparian areas, wetland margins, forest understorey, wasteland, farmland, roadsides, grasslands.
Seeds dispersed by birds. Vegetative spread from stolons and rhizomes.
Forms dense clumps, outcompeting native plants. Stinging leaves can cause pain and swelling. May impede access to natural areas.
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.
