Tetragonia, Warrigal greens, or New Zealand spinach, is a low growing, perennial, edible groundcover with a trailing habit. It grows in poor, dry conditions, but an open position with moist, light fertile soil will produce a flourishing plant. It is frost sensitive.
This plant is also native to Australia, New Zealand, Japan, Chile and Argentina, and is not related to true spinach, but the leaves can be used in a similar way. Like true spinach, it is high in iron, beta carotene and folic acid, and like spinach, it contains oxalates. The oxalates can be lessened by blanching in very hot water and draining off the water before use.
