Sunn hemp (Indian-hemp) is a fast-growing tropical legume commonly used as a green manure, cover crop, and fiber plant. Provide full sun and well-draining soil with regular watering during active growth for best results. It fixes atmospheric nitrogen, making it a valuable addition to garden beds and agricultural systems, but note that seeds and plant parts can be toxic if ingested.
