Cestrum spp are not a legally declared Pest Plant in New Zealand but they are extremely toxic to farm animals.  It originates from Chile and Peru and is a relative of the potato family.
It is a vigorous, erect, perennial shrub <3m tall but more commonly 1-2m. It is long-lived and partly deciduous in winter. It habitats are waste areas, stream banks, near gardens, bush margins, gullies, alluvial flats. Dense infestations exclude virtually all other vegetation. Prefers higher rainfall areas and is very frost tolerant. Its seeds are dispersed by birds & water. Pieces of cut root will spread by cultivation. It will also reproduce vegetatively from buds from creeping roots. Seeds remain dormant in the soil for many years.
