The wild orange is an Australian native plant found in dry inland areas of Australia. Its scientific name is Capparis mitchellii. It is not related to oranges, nor to the Osage-orange which is known as "wild orange" in North America, but to capers.

Bush tucker, also called bush food, is any food native to Australia and historically eaten by Indigenous Australians, the Aboriginal and Torres Strait Islander peoples, but it can also describe any native flora, fauna, or funga used for culinary or medicinal purposes, regardless of the continent or culture. Animal native foods include kangaroo, emu, witchetty grubs and crocodile, and plant foods include fruits such as quandong, kutjera, spices such as lemon myrtle and vegetables such as warrigal greens and various native yams.
