Columbus grass

<em>Sorghum almum</em>, commonly known as Columbus grass, is a robust perennial grass in the family Poaceae. It thrives in disturbed habitats, roadsides, agricultural margins, and open grasslands, demonstrating a strong preference for warm climates and well-drained soils. The species has been introduced and naturalized across many tropical and subtropical regions beyond its original South American range, and is cultivated in parts of Africa, Asia, and Australia as a forage grass. It produces tall, erect culms that can reach several meters in height, bearing broad leaf blades and open, branching panicles with numerous spikelets. Columbus grass is valued for livestock fodder but is also regarded as an invasive weed in certain agricultural contexts due to its vigorous growth and capacity for vegetative spread via rhizomes. Biological metrics including lifespan, length, and weight data are not available in the current record.
