Not a nut at all. A legume related to beans. Annual crop sown in spring, harvested in autumn. After pollination, the flower stem (peg) grows downward into the soil where the pod develops underground. Needs a long, warm growing season (4-5 months frost-free). Easy to grow in warm zones with sandy soil. As a legume, fixes nitrogen and improves soil. Two main types: runner (spreading, commercial) and bunch/Spanish (compact, better for small gardens).

How to harvest: Pull entire plant from soil (loosen with fork first). Shake off soil. Check pods are mature. Hang plants upside down in dry, ventilated area for 1-2 weeks to cure.
Expected yield: 20-40 pods per plant depending on type
