We recently undertook an expedition from western Sydney to the Royal Botanic Garden (RBG), Sydney.
Two features were of particular interest. One was the newly established southern African terraced garden. This garden features Cycads and various members of the African Proteaceae family.
When the Proteaceae specimens flower it is easy to see the close relationship with Australian members of the family.
Once this garden matures it will provide an excellent representation of the southern African flora.
The other garden of great interest was the Australian Native Rockery. This extensive rockery is beside the path that leads to the Opera House and was renovated and replanted for the Sydney Olympics.
The garden is filled with a wide range of natives including Gymea Lilies, banksias, grevilleas and everlasting daisies.
The plants that drew our attention were many specimens of a prostrate Casuarina. These plants spilled over the sandstone rocks that are the building blocks of the rockery. Casuarina glauca “Shagpile” (see image) develops into a dense, weed suppressing ground cover that would be suitable for many garden situations.
