Sheep sorrel is native to Europe and Asia but has been naturalized in North America. It’s a common weed in fields, grasslands, and woodlands. It flourishes in highly acidic soil. Sheep sorrel has a tall, reddish stem and can reach heights of 18 inches. Sheep sorrel contains oxalates and shouldn’t be eaten in large quantities. You can eat the leaves raw. They have a nice tart, almost lemony flavor.
Wild mustard is found in the wild in many parts of the world. It blooms between February and March. You can eat all parts of the plant- seeds, flowers, and leaves.
You’ll find wood sorrel in all parts of the world; species diversity is particularly rich in South America. Humans have used wood sorrel for food and medicine for millennia. The Kiowa Indians chewed on wood sorrel to alleviate thirst, and the Cherokee ate the plant to cure mouth sores. The leaves are a great source of vitamin C. The roots of the wood sorrel can be boiled. They’re starchy and taste a bit like a potato.
