Dear Nature Lovers,
Greetings from oikos !

Saccharum spontaneum is a tall perennial grass 
growing in wetland habitat or damp places or 
even along river banks; usually in sheltered places.
It has creeping rootstock and deep rooted clumps so good soil binder.
It is used for decoration, thatching, making ropes and as fodder. 
It does not produce sugar but it used in sugar cane breeding; 
hybrids between it and cultivated sugar cane (Saccharum officinarum)
It flowers after rain and its caryopses i.e. seeds are dispersed by wind.
It many a times become serious threat in agricultural lands.
So need management in case of agricultural systems.
