Figure 7-25. Watercress.
Wild onion.
Wild onions are found throughout the United States, except in the hot and dry
areas. They are found on the plains, hills, and mountains, usually in open areas, and all have the
characteristic onion or garlic smell. Its bulb is usually reddish purple, and the plant has tall
slender stalks with a typical allium cluster of flowers. Avoid all onion look-alikes that do not
have a strong onion smell when the leaves are crushed, because they may be poisonous.
