An unusual (to me) tree on the street where my daughter lives, in the northern suburbs of Sydney.

  Melaleuca quinquenervia is commonly known as the broad-leaved paperbark, broad-leaved tea tree or simply paperbark or tea tree in Australia, and as punk tree in the United States.

Besides being the source of tea tree oil, the tree has many uses, especially to aboriginal Australians.  See Uses and Cultivation in Wikipedia.

It is regarded by the United States Department of Agriculture (USDA) as an invasive weed in Florida where it was introduced to drain swamps.
