- Parkinsonia is thought to be native to tropical America but has spread throughout the world as an ornamental and shade tree.
- As Parkinsonia is adapted to an extremely wide range of soil types, there is little doubt that it will continue to spread through watercourses and adjoining areas throughout the sub-humid and semi-arid environments of Queensland.
