Modern chefs have transformed this historically disliked vegetable into a much-sought-after food that is delicious deep fried, steamed, or roasted. Give them plenty of water, nutrients, and time to grow before they begin forming sprouts. Covering plants with row covers after sowing/transplanting will help exclude pests. You can leave plants in the garden into the winter, as they are hardy to 10��F; frost actually improves the flavor. The plants resemble little palm trees.
