I was most intrigued by the ubiquitous banksia tree that produces flower spikes that turn into hard cones. In this picture you can see both states next to each other on a live tree. Unfortunately Banksia trees - like other Eucalyptus trees - are very vulnerable to Dieback disease.

Australia is suffering a lot from invasive plants. Blackberries is a good example for that: They were intentionally introduced into Australia in the mid 1800s and soon turned into a pest. You will see blackberries a lot along the trail but be careful with eating them: Very often they are sprayed with pesticides - although warning signs will tell you.
