Indian Grass, (Sorghastrum nutans)
When we started converting our old pastures back into stands of native warm season grass a couple decades ago we picked the two dominant grasses: Big Bluestem and Indian Grass.
What we have learned is that on our property Indian Grass tends to take over. It overwhelms the other grasses and flowers. We have not figured out how to control that. If you are considering adding warm season grasses I would caution you about using Indian Grass.
