Johnsongrass is a grass of the sorghum family. It is native to the Mediterranean region, but grows throughout Europe and the Middle East, and was introduced to the United States about 1830. It can now be found in every state except Minnesota, Maine, and Alaska. It reproduces by rhizomes and seeds.

Johnsongrass has been used for forage and to stop erosion, but it is often considered a weed.

The Kiowa used Johnson grass as fodder for horses, and Kiowa children used the stems and leaves to make grass whistles. (From Wikipedia)
