Maytenus boaria is an evergreen, dioecious tree of the family Celastraceae, native from Chile and Argentina in South America. It was introduced to New Zealand in 1881 and after being sold commercially in the 1920s it is now naturalised in several areas. It has been banned in New Zealand after it was listed as invasive species. It is now illegal under the Biosecurity Act to propagate, distribute or sell this plant - either casually or through nurseries - but existing plants are still allowed on private properties.
Maytenus boaria spreads aggressively by root suckers and seed.
