Sturt's desert pea is the Australian outback's most dramatic wildflower, large, blood-red pea flowers with a glossy black 'boss' (raised central structure) that seem almost too vivid to be real against the red desert sand. After rain, they carpet vast areas of the arid interior in a spectacle that stops travelers in their tracks.

Aboriginal Australians associate it with stories of blood and sacrifice, the black 'boss' in the center represents a place of mourning in several Dreaming stories.
