Where has tree tobacco become naturalized outside South America?

Tree tobacco (Nicotiana glauca), a plant species native to South America, has become naturalized in several regions outside its original range. Specifically, it is established in parts of the southwestern United States, Australia, and southern Africa.1

It is important to note that while this plant is often found in these areas, it is also recognized for its toxicity and can be responsible for the poisoning of livestock.1
