Some native Australian seeds have evolved some specialised strategies for reproduction. The way they do this and the reasons why can give gardeners some clues about how to propagate native plants from seeds.
In the case of woody plants, their seeds remain on the plant indefinitely and need fire to release the seed – examples of these are Banksias, Tea tree, bottlebrushes and eucalypts. These seeds can be collected at any time and to propagate them all you need to do is put the seed pods in a paper bag and place it in a warm dry place (such as on top of a heater). After a few days the seeds will have been released by the pods and you can sow them. With Banksia seeds you can also place them in an oven on low heat which will cause the pods to open and release their seeds.
