Etymology
euonymus: One possible explanation is this genus is named after Euonyme, the mother of the Furies (vengeance deities in Greek mythology) because of the irritating properties of this plant. Another explanation is that the name is simply from the Greek eu ‘good’ and onoma ‘name’, meaning ‘a name of good repute’.
japonicus: From Japan

Environmental Weed (2024)
This plant is named in a list of 386 environmental weeds in New Zealand 2024 prepared by DOC. 759 candidate species were considered for inclusion on this new comprehensive list of environmental weeds in New Zealand. The species considered were drawn from published lists of weed species, lists of plants that must be reported or managed by law if observed, existing national and regional programmes and agreements for pest management, and species already managed by the Department of Conservation (DOC). Candidate species were then assessed to see if they were fully naturalised and whether they have more than minor impacts in natural ecosystems. Read the full report here.
