Miscanthus × giganteus (
Miscanthus giganteus, giant miscanthus) is a highly productive, rhizomatous C4 perennial grass, originating from Asia. It is a sterile (noninvasive)
hybrid of
M. sinensis and
M. sacchariflorus, and grows to heights of more than in one growing season (from the third season onwards). In temperate climates such as in Europe, the dry mass
yield is per year, depending on location. Just like
Pennisetum purpureum and
Saccharum ravennae (which grow to the same height), it is also called "elephant grass". Miscanthus' ability to grow on marginal land and in relatively cold weather conditions, its rapid absorption, its significant
carbon sequestration, and its high yield make it a favorite choice as a
biofuel. Miscanthus is mainly used for heat and power, but can also be used as input for ethanol production (if harvested wet). If harvested dry, it can be burnt directly in biomass boilers, or processed further (pellets, briquettes). It can also be used as a "green" building material, for both wall construction and as general insulation. An experimental house based on
Miscanthus straw bales was built in 2017. Miscanthus cropping enhances
nutrient cycling in the plant–soil system. In a 2025 research dried stems of Miscanthus giganteus, together with other materials, were used to create a biobased concrete substitute called Xiriton, which offers a low-carbon, eco-friendly material that can support shellfish settlement and salt-marsh restoration. ==References==
