Did you know that the goldenrod, genus Solidago, is edible? This plant is not only edible but is also well known for its healing properties (Edible Wild Food). All aerial parts of the plant can be eaten (Edible Wild Food). One website recommends using the flowers as a garnish on a salad and cooking the leaves like spinach (Edible Wild Food). Other uses include using the flowers and leaves to make a bitter tea (Edible Wild Food).
