Edibility
The leaves are edible as a salad green when young and tender, but they quickly become tough and fibrous as they get older. The older leaves can be cooked in stews. The leaves contain calcium and other minerals, with 100 grams of plantain containing approximately the same amount of vitamin A as a large carrot. The seeds are so small that they are tedious to gather, but they can be ground into a flour substitute or extender.
