(Tetragonia tetragoniodes) A cousin to regular spinach. New Zealand Spinach is a heat loving plant, which is at its peak in the summer after other greens have bolted and lasts all the way until a fall frost. Delicious raw in salads, or replacing spinach in any recipe (think spanakopita!). The plants are low and spreading, with tender green leaves that resemble spinach in appearance and texture. Native to the sand dunes and shorelines of New Zealand, Australia and the Eastern Pacific.
