Native to Europe and Asia, kochia is a small annual plant. It was grown as an ornamental hedge around gardens and is sometimes sold in nurseries under the name 'burning bush', due to its red-tinged foliage at certain times of year. It is a serious weed of crops in North America. While it is not known to exist in Queensland, it has the potential to become a serious pest if it is ever introduced and planted.
Kochia is a prohibited invasive plant under the Biosecurity Act 2014.
