Quote: "Dock - a perennial weed in the buckwheat family. In early spring basal leaves emerge from a stout taproot. By summer the plant has reddish & rigid stems 2-4 ft tall; then flower stems show up with greenish flowers. There are 2 types of dock (curly and broadleaf). As an edible plant, its leaves are rich in vitamins A and C, containing an easily digested iron that is essential. Use the youngest leaves in salads and the older leaves for teas or stir fries."
