Lamb’s-quarters is a tall weed related to beets and spinach. It is found in fields and gardens and along roads in most of North America, Europe, and Asia. The plant ranges in size from 1 foot (30 centimeters) to 10 feet (3 meters). Tiny greenish flowers grow in small clusters on the upper part of the stem. Lamb’s-quarters is also called pigweed, goosefoot, or fat hen. It is a nuisance to farmers because the seeds become mixed with grain seeds. The leaves can be cooked and eaten.
