Genus: Saccharum

About this species

Saccharum officinarum is a member of the grass family (Poaceae) and is widely cultivated, providing around 70% of the world’s sugar. Sugar cane yields the highest number of calories per unit area of cultivation of any plant.

Sugar cane probably originated in New Guinea, and was taken to the Americas by the explorer Christopher Columbus on his second expedition there in 1493. Sugar cane is now grown in more than 70 countries, mainly in the tropics, but also in some sub-tropical areas. India and Brazil produce about half the world’s cane sugar.

The word 'sugar' is thought to derive from the ancient Sanskrit 'sharkara'.

Geography and distribution

Harvesting the Sugar-Cane in Minas Geraes, Brazil, painting by Marianne North

Sugar cane is grown in southwestern Europe, Africa, temperate Asia, tropical Asia, Australia, the Pacific, southeastern USA, Mexico, and South America. It has been cultivated in New Guinea since about 6000 BC, and, from about 1000 BC, it was gradually spread along human migration routes to Asia and the Indian subcontinent. 


Overview: A tall grass, which looks rather like a bamboo cane, and grows 3-6 m high with culms (stems) 20-45 mm in diameter.

The thicker-stemmed forms are commonly known as 'thick' or 'noble' canes because of their tall, handsome, colourful stems.

Leaves: Broad (up to 6 cm wide), 70-150 cm long, borne alternately on the stem, with leaf base encircling the stem.

Fruits: An oblong caryopsis (small, dry, one-seeded fruit), 1.5 mm long.

Saccharum officinarum can be recognised by its hairless or short-haired panicle axis, and leaf-blades up to 6 cm wide.

Other species of Saccharum

Besides Saccharum officinarum, four other species in the genus Saccharum have been used for sugar production:

  • S. barberi, known as 'Indian cane' or 'thin' cane
  • S. robustum
  • S. sinense, known as 'Chinese cane'
  • S. spontaneum, which is known as 'wild cane' and used for hybridisation purposes


Early uses - chewing

Sugar cane was originally grown in southeastern Asia and the Pacific for the sole purpose of chewing. The rind was removed and the internal tissues sucked or chewed. The production of sugar by boiling cane juice first took place in India, most likely during the first millennium BC.

Food and drink

Sugar is now a highly valued food and sweetener and also serves as an edible preservative. Raw and refined sugars are produced by heating, removing impurities and crystallising sugar cane juice, which mainly consists of sucrose.

Raw and refined sugars are exported all over the world for use in sweet and savoury dishes, processed foods and drinks and for preserving fruits and meat. They are also compressed into sugar cubes and made into syrup. White sugar can be further processed (ground into a fine powder) into icing sugar, which is used in desserts, baking and confectionery.

In India, the young shoots of sugar cane are sometimes steamed and roasted as a vegetable.

Medicinal uses

Sugar cane has also been used medicinally. In southern Asia it has been used to treat a wide variety of health complaints from constipation to coughs, and has been used externally to treat skin problems. Both the roots and stems are used in Ayurvedic medicine to treat skin and urinary tract infections, as well as for bronchitis, heart conditions, loss of milk production, cough, anaemia, and constipation. Some texts advise its use for jaundice and low blood pressure.

Sugar paste has been widely used to pack wounds and aid healing.

Hair removal

Sugar is used for hair removal, in a practice that is thought to date back to the ancient Egyptians. A warm paste of sugar, water and lemon juice is applied to the skin. Strips of cloth are then pressed over the paste and torn off quickly, taking the hair with them. Sugar is also used in soap-making and as an abrasive scrub to exfoliate skin.

Molasses and alcohol production 

A by-product of sugar refining is molasses, which is a dark, syrupy product used in the preparation of edible syrups and for numerous industrial products. It is used for animal feed, fertilizers, and even for adding to tobacco for hookah pipes and some cigarettes. Molasses, along with cane juice and other by-products of sugar production, can be fermented and then distilled, to produce rum.

Pure alcohol (ethanol) can also be produced from molasses, and is used in the preparation of vinegar, cosmetics, pharmaceuticals, cleaning preparations, solvents, and coatings. Ethanol produced in this way (bioethanol) is widely used in Brazil and the USA as a motor fuel, as part of a movement to use sustainable alternatives to petrol. Other products produced from molasses include butanol and lactic acid (solvents), citric acid (used in foods and drinks), and glycerol.


By-products of sugar cane processing

The fibrous cane residue left after processing is known as bagasse and is used as fuel to generate energy for the sugar manufacturing process. It also serves as a fibre for making paper. The fibre is separated from the pith, which itself can be used as an animal feed. Filter cake, consisting of cane juice, impurities and lime, is used as a soil improver.


Sugar cane is successfully propagated in Kew’s Tropical Nursery using cuttings taken from the cane and then laid flat. The plants require large pots due to their extensive root system.

Sugar cane benefits from regular feeding and a large volume of compost. A standard Kew mix containing 10% loam, 45% coir and 45% Silvafibre with added fertiliser is used, and is kept moist.

The glasshouse zone in which sugar cane is grown has a minimum temperature of 14˚C and high light intensity. Under good light conditions the plants grow strongly and do not require staking.

Sugar cane can suffer from red spider mite infestations, which can cause considerable damage to leaves.

Sugar cane at Kew

Saccharum officinarum is on display in Kew’s Palm House, where many tropical economic plants can be seen.

Pressed and dried specimens of sugar cane are held in Kew's Herbarium, where they are available to researchers by appointment. Details of one of these specimens can be seen online in Kew's Herbarium Catalogue.

Kew's Economic Botany Collection is home to over 30 specimens of sugar cane and related products. These include sugar, syrup, wax, molasses and even toilet paper made from S. officinarum.
