Point of Interest 7: Orchids Sign

This area has banksia woodland over shrubs and herbs close to a large dead banksia and healthy Menzies Banksias. This spot is close to the interpretive sign featuring Red Beak and Blue Sun Orchids. It is a good place to see Dwarf Wedding Bush flowering in spring, as well as Running Postman and Marno in winter.

Focus Topic 15. Menzies Banksia

The Menzies or firewood banksia (Banksia menziesii) produces impressive red and yellow flower spikes in winter, providing an important food source for insects and birds at that time. Each spike contains hundreds of tiny red flowers with yellow stigmas, which are primarily insect pollinated but also attract birds. Carnaby’s Black Cockatoos (Calyptorhynchus latirostris) feed on the seeds and nectar and seek out grubs in the flowers (Focus Topic 10). Relatively large and complex galls are common on banksia trees and are formed by very small insects that have not yet been identified.


The nectar of banksia flowers was also used in a drink by the local aboriginal people (the Whadjuk Noongar). Along with beverages from other flowers, such as grevillea, it was drunk at special sweet water festivals.


Focus Topic 16. Running Postman

Running Postman (Kennedia prostrata) is a late winter and spring flowering pea that often becomes more dominant after fire, but also grows in long unburnt areas. This nitrogen fixing disturbance opportunist has a key role in rebuilding soil fertility after fire (Focus Topics 25 and 28). Due to their rapid growth, they sequester other nutrients such as phosphorus to avoid loss from soil after fire. This ground-cover plant also effectively smothers weeds. The large red flowers are typical of bird pollinated plants. Birds see this colour well, but many insects only detect shorter wavelengths of light (ultraviolet through to orange).
