There are many varieties of this annual plant throughout much of Australia, from deserts to farming country.
This purple touched one is Pink Mulla Mulla or Ptilotus exaltus. I’m unsure about the naming of the yellow-tipped white Mulla Mulla next to it.
I’m unsure about the name of this one as well. It is just another of the Mulla Mullas. So common and so unusual that they are often overlooked.
