Tetragonia tetragonioides: is a member of the Aizoaceae family. Warrigal Greens and New Zealand Spinach are two recognised common names.
Tetragonia tetragonioides is a prostrate, sometimes short-lived perennial. The leaves are diamond-shaped, up to 10 centimetres long by five centimetres wide. The insignificant flowers are green or yellow. They are followed by small, woody, winged fruits.
Warrigal Greens has along history as an edible Australian native plant. Captain Cook collected the species in New Zealand and used the plant as a fresh vegetable, on board ship, for protection against scurvy.
Sir Joseph Banks took seeds back to England where it was grown in Kew Gardens. The species became popular as summer spinach in England and America. At the height of its popularity the species was known as Botany Bay Spinach.
The plant fell out of favour but, in company with other bush tucker plants, is becoming popular again.
Tetragonia tetragonioides is found throughout all mainland states, except the Northern Territory, as well as Lord Howe Island and New Zealand. The seeds float and may have been carried on ocean currents to Lord Howe Island and New Zealand.
Propagate from seed or cuttings.
