Claytonia (also called Winter Pursulane or Miner’s lettuce) is a really useful, hardy, heart-shaped winter salad green that can be used to bulk-up winter salads and stir fries, and can still be sown even at this late time of the year. It was called Miner’s lettuce after the Goldrush miners who valued its high vitamin C content to ward off scurvy.

One hundred grams of claytonia contains one-third of your daily requirement of Vitamin C, 22% of the Vitamin A, and 10% of the iron. So this little leaf packs a nutritional punch.
