This is a beautiful specimen of Banksia occidentalis, that I saw growing in a private garden in south west Sydney.The colour contrast between the new flower and the mature flowers is striking, it almost looks like two different plants. This was growing on a high mound for extra drainage and the natural soil had been carefully added to. As Banksia occidentalis comes from WA it dislikes the humid summers of the east coast and is therefore an unreliable shrub, however definitely worth a try if you are keen, makes a great screen or feature.
