Little Hogweed is a spreading plant with succulent, often reddish stems and succulent, spoon-shaped leaves; the flowers are small and yellow and open only on hot, sunny days. It is considered a beneficial weed because all parts of the plant are edible, raw or cooked. It is quite nutritious because it is unusually high in omega-3 fatty acids and contains significant amounts of vitamins A and C, as well as calcium, iron, magnesium and potassium and antioxidants. It is sometimes used as fodder and is fed to poultry to reduce egg cholesterol. It was used traditionally as an ointment for burns. Source.
