Wild sugarcane (Saccharum spontaneum)

Wild sugarcane, Saccharum spontaneum, is the tall reed whose silvery-white plumes fill Indian riverbanks and fallow fields after the monsoon — the kash phool of Bengal and the nanal of Tamil. It is a wild relative of sugarcane, too thin and fibrous to crush for juice, and it quietly helped build India’s modern sugar industry.

How to recognise Wild sugarcane

It grows in dense clumps two to four metres tall from creeping underground stems. The leaves are long and narrow, with a white midrib and sharp, rough edges.

From late monsoon into autumn it carries soft, feathery, silvery-white plumes. In Bengal their appearance is the traditional sign that Durga Puja is near.

The stems are thin, hard and pithy. Noble sugarcane, Saccharum officinarum, has thick, juicy, often coloured stems and is grown only as a crop.

Modern notes on Wild sugarcane

Breeders at the Sugarcane Breeding Institute in Coimbatore crossed it with noble cane in the 1910s and 1920s. The hardy hybrids that resulted, including the famous Co 205, transformed Indian sugar yields, and most modern cane varieties carry its genes.

Its deep rhizomes bind riverbank soil, which makes it useful for erosion control and hard to remove from fields.

Wild sugarcane safety

The leaf edges cut skin, so wear gloves when handling it.

Ecology and sourcing

Tall stands of it form the grasslands of the Terai and Brahmaputra floodplains that shelter rhinoceros, swamp deer and hog deer.

Outside Asia it can be aggressively invasive. In Panama it is known as canal grass for the way it took over cleared land.
