M. sinensis is widely cultivated as an ornamental plant, and is the source of several cultivars. In Japan, where it is known as susuki, it is considered an iconic plant of late summer and early autumn. It is mentioned in Man'yōshū as one of the seven autumn flowers. It is used for the eighth month in hanafuda playing cards. It is decorated with bush clover for the Mid-Autumn Festival. Miscanthus has also excellent fiber properties for papermaking.

''Hybrid: Miscanthus x giganteus''

Miscanthus x giganteus
is a highly productive, rhizomatous C4 perennial grass, originating from Asia.
It is a sterile hybrid of M. sinensis and M. sacchariflorus, and grows to heights of more than 4 meters in one growing season. In temperate climates like Europe the dry mass yield is 10-40 tonnes per hectare per year, depending on location.
Just like Pennisetum purpureum and Saccharum ravennae, it is also called «elephant grass».
Miscanthus' ability to grow on marginal land and in relatively cold weather conditions, its rapid CO2 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 dry, Miscanthus can be burnt directly in biomass boilers, or processed further. 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.
