Uses
Rumicastrum balonense is recorded in the 1889 book The Useful Native Plants of Australia as being called "periculia" by Indigenous Australians and that the plant was eaten by Europeans with bread while Indigenous Australians used it as a food when mixed with baked bark. "The seed is used for making a kind of bread, after the manner of that of Portulaca oleracea. (Mueller, Fragm., x., 71.)."
