What you need to know

Although inkweed is not a legally declared pest plant, it may still be invasive in some situations. Consider lower risk alternatives for your garden, such as native plants.

Disturbed forest and shrubland, grassland, cliffs, coastal areas, riparian margins, wasteland, roadsides.

Seeds dispersed by birds and water.

Can form dense stands in open areas and suppress native seedling recruitment.

Site Management

Will quickly become succeeded by taller native species so only control in open or sensitive 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.
