Sunn Hemp

Crotalaria juncea
Sunn Hemp (Crotalaria juncea) is an annual forb native to southern US states (such as Florida, Texas, and Louisiana) and has also been successfully introduced across North America as a non-invasive crop that can thrive in USDA Zones 8–11 as a warm-season annual. Reaching a mature height of 4–6 feet with an upright branching growth habit, it features narrow, velvety green leaves and produces bright yellow pea-like flowers. It thrives in well-drained sandy to loamy soils in full sun and is ideal for soil nitrogen enrichment, nematode control, and agricultural cover cropping.
