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).
