New Zealand spinach, also known as warrigal greens or Botany Bay greens, is an Australian and New Zealand native plant that produces thick, succulent-like triangular leaves with a spinach-like flavour. Unlike true spinach, it thrives in heat and poor soils, making it the ideal summer leafy green for Australian gardens. It was historically eaten by Indigenous Australians and was collected by Joseph Banks during Cook's first voyage.
