Notes: | Spread by: ‘seeds’: running water, contaminated feed, coats of animals, contaminated machinery and wind for short distances. Invades/threats: permanent pastures on fertile soils. Notes: introduced as an ornamental. To date only recorded from a few locations in this region. New outbreaks should be reported immediately so that appropriate control measures can be undertaken. Aggressive and very competitive; seed banks build up in soil; able to germinate and grow through even thick healthy pastures. Hairs on leaves and stems cause irritation if touched. Category 3 restricted invasive plant under the Biosecurity Act 2014, it must not be given away, sold, or released into the environment without a permit. The Act requires everyone to take all reasonable and practical steps to minimise the risks associated with invasive plants and animals under their control.
