Where does Johnson grass grow?

Johnson grass (Sorghum halepense) is commonly found in warm, temperate regions, particularly in the southeastern United States, but it can also grow in other areas with similar climates. It thrives in disturbed soils, such as roadsides, agricultural fields, and pastures. The grass prefers sunny areas and can tolerate drought, making it a resilient species in various environments. However, it is often considered a problematic invasive species due to its ability to outcompete native plants.
