Elephant grass is a robust, rhizomatous, tufted perennial grass. It has a vigourous root system, developing from the nodes of its creeping stolons. The culms are coarse, perennial, and may be up to 4-7 m in height, branched above. Elephant grass forms dense thick clumps, up to 1 m across.
It is marvellous to see one jump up and down in five foot high elephant grass, he almost seems to hover in the air at the top of his jump while he has a quick look round and scents the air: hence one of the African names, mbwa mkube mbwa wamwitu - the jumping up and down dog.
