    A native of Australia, Waterhousea floribunda grows up to 30 metres in height and has attractive weeping branches, which are used for shade and shelter. This tree has been introduced into French Polynesia and has become invasive on the Island of Moorea. The fruit is eaten and dispersed by birds; a fact to be mindful of when considering control methods or preventative measures for this plant.
