New Zealand Spinach

(Tetragonia expansa) First introduced to English gardeners in 1772 by Sir Joseph Banks. Reportedly discovered during the South Seas Expedition of Captain Cook. Native to New Zealand and Australia. Can be grown as a perennial in warmer climates, but typically grown as an annual. Not a true spinach, but the leaves taste very similar, and some think even better than spinach. Does not bolt or turn bitter. High in vitamin C. Edible leaves starting at 60 days and continuing until frost.
