Sorghum × drummondii, commonly known as Sudan grass, is an annual grass hybrid used primarily for forage and grain. It is native to the grasslands and savannas of Eastern Africa but has been widely cultivated in warm regions around the world, including Southern Europe, South America, Central America, North America, and Southern Asia. This species typically grows quickly to a height of 2-8 feet (0.6-2.4 meters) and has a notable tolerance for drought and heat.

Sudan grass is valued for its rapid growth and high biomass production, making it a popular choice for green manure, cover cropping, and as a natural weed suppressant. It is also used for grazing, hay, and silage due to its palatability and nutritional value for livestock. Sudan grass thrives in full sun and is adaptable to a variety of soil types, though it prefers well-drained soils. It requires minimal water once established, making it suitable for arid climates. However, it can become weedy and potentially invasive, so it is important to manage its growth and prevent unwanted spread.CC BY-SA 4.0
