Pittosporum is a genus of about 200 species of flowering plants – probably Gondwanan in origin – that extends across Australasia, Oceania, eastern Asia and some parts of Africa.  They are commonly known as ‘cheesewoods’.

The weeping pittosporum (Pittosporum phillyraeoides) after which the Rockhole is named is native to the warmer inland, and is an extremely useful tree for planting in streets, parks and gardens in all low rainfall areas. It grows to 4-10 metres and produces yellow flowers July to November.
