This isn't the Old Man Saltbush I wrote about earlier this week. It's a Ruby Saltbush, a common plant in the drier parts of Victoria.
But the Ruby Saltbush Enchylaena tomentosa var. tomentosa looked quite comfortable in the heat and arid environment. The brightly coloured 'berries' and succulent leaves are edible, and were an important antiscorbutic vegetable for some early explorers of Australia. (I had to look up 'antiscorbutic' - it means they ate it to guard against scurvy.)
I wonder why the birds haven't eaten the berries.
