A non-invasive clumping type grass that does not produce viable seed. Excellent for erosion control as it produces a massive root system that grows straight down rather than out from the plant. It creates a sort of curtain beneath the soil, trapping sediment and slowing down the movement of water. Because the grass grows down instead of outward, it does not become invasive. The roots are very deep, so its best to decide carefully where to plant it because it is very hard to dig up. Watch this Youtube to show a great idea of hedging Vetiver and using it as mulch.
