Brad Lancaster describes the strip of vegetation beside the sidewalk outside his Tucson, Arizona home as “an orchard and a pharmacy.” The desert ironwood tree has peanut flavored seeds and blooms that make a delicious salad garnish. Creosote is good for athlete’s foot. Chuparosa has a red flower that tastes like cucumber. The barrel cactus’s yellow fruit can be used for chutneys or hair conditioner. Mesquite pods make nutritious flour. And many more. Depending on the season, Lancaster gets 10 to 20 percent of his food from this sidewalk garden, and another in his yard.
