IndiangrassIndiangrass

Scientific name:  Sorgastrum nutans L.  

Description: Indiangrass is a native perennial, warm-season tallgrass, which reproduces from seed and short underground stems. It produces beautiful golden plume-like seed heads on stems that reach heights of 4 to 8 feet tall. It is easily identified by the claw-like ligule where the blade attaches to the sheath. Indiangrass is used for green forage or dry prairie hay and is very nutritious. It should not be grazed shorter than 5 to 8 inches during the growing season. It is found throughout the Bluestem belt of the United States, and can be seeded alone or in mixtures with other tall grasses.
