I absolutely love the green wall on the ANZ building in Docklands which is featured in the banner of Ideas for cities from cities.
I particiulary like the use of ficinia nodosa, or knobby club sedge. This plant is found on the dunes at Port Melbourne and also looks good as a landscape plant in front of the Beacon Cove towers where it has just had a tidy trim.
