There are several species of Miscanthus, each with distinct characteristics and uses. The most notable include:

Miscanthus x giganteus

Description: A sterile hybrid, resulting from a cross between Miscanthus sinensis and Miscanthus sacchariflorus.
Uses: Primarily grown for biomass production, bioenergy, and as a raw material for bioproducts.
Growth: Can reach heights of up to 4 meters and produces high yields of biomass.

Miscanthus sinensis

Description: Also known as Chinese silver grass, it is widely used for ornamental purposes.
Uses: Popular in landscaping due to its attractive foliage and plumes.
Growth: Typically grows to about 2 meters and is known for its hardiness.

Miscanthus sacchariflorus

Description: Known as giant silver grass, it is native to Japan and Korea.
Uses: Used for soil stabilization and as a biomass crop.
Growth: Can grow up to 3 meters and spreads via rhizomes.

3. Cultivation and Growth
