These are imposing, mainly deciduous, clump forming grasses, of both large and small stature.
There are up to 20 species from Southeast Asia to Africa, growing in marshes and open land. Miscanthus is a close relative of sugar cane (Saccharum) and can be useful as a biomass fuel, when the two are hybridized.
They will tolerate all conditions, but severe drought will curb their growth. They flower late in the autumn, so are a good addition to the winter border. Cut back in the spring.
