Switch grass is best known by its wide open, airy seed heads. It forms dense stands, and can be aggressive. It is commonly used in conservation plantings.

Like other deep-rooted prairie plants, its roots help build soil, stem erosion and filter out agricultural chemicals before they reach waterways. 

In Iowa, experiments are underway in which switch grass is baled and burned in power plants in combination with coal to produce electricity.

Switch grass can be located at local plant nurseries, and is usually sold under the name "Heavy Metal." It can be quite beautiful in a prairie garden, and provides winter interest because it stands tall until spring.
