Urban foraging involves a keen knowledge of edible plants and fungi, as well as an understanding of what is safe and legal to harvest. These foragers often seek out wild-growing greens like dandelion, plantain, and chickweed, which can be used in salads, teas, or as a garnish. Mushrooms, when properly identified, may be another exciting discovery, providing flavors that can't be found in typical grocery stores. Fruit-bearing plants, such as wild blackberries, apples, and even urban trees like mulberries, are often harvested during their seasons, offering delicious, free food.
