Cananga odorata

Common name: Cananga

Other common names: Matches stick tree, Ylang ylang

Names in non-English languages: Philippines India Spanish


Cananga or Ylang ylang is a flowering and essential-oil yielding tree originating from Southeast Asia and the Pacific, its natural range extending from the Philippines, through Indonesia and Papua New Guinea, to northern Australia and from Vietnam through Cambodia to Thailand and Malaysia. It is now introduced in nearly all, if not all, tropical countries of the world and is cultivated in Indonesia, the Comoro Islands, Reunion and Nosy Be (in Madagascar) for its flowers, which are distilled for an essential-oil.

It is a fast-growing tree and in parts of its range may reach up to 40 m (130 ft) tall with a trunk diameter of 75 cm (2.5 ft). In cultivation, it is more typically 3 to 10 m (10 to 33 ft) tall with an irregular crown of long, slender wide-spreading branches, some of which extend out so far they droop. The bark is light brown or greyish, smooth in young trees, in mature trees fissured and rough.

The leaves are elongated oval with a pointed tip, up to 20 cm (8 in) long, dark glossy green and prominently ribbed on top, underneath pale dull green. They remain on the tree in all seasons and are alternately arranged along slender branches that extend out as much as 6 m (20 ft), causing them to droop under their weight.

The flowers are large, made up of six slender petals up to 13 cm (5 in) long that are green and twisted when young, becoming yellow, limp and drooping when mature. They are borne in profusion, in clusters of four to twelve arising at the leaf bases and come into bloom in the rainy season but may bloom continuously in areas without a distinct dry season. When mature they are overpoweringly sweetly fragrant, reminding of Arabian jasmine (Jasminum sambac) and Royal jasmine (Jasminum grandiflorum).

The fruit are oval, up to 2.5 cm (1 in) long, green when young, becoming blackish when ripe and are berry-like, with up to twelve small seed embedded in yellow pulp.


The flowers yield a sweetly fragrant essential oil traded as 'Ylang ylang oil' or 'Cananga oil', extracted using either steam distillation or solvent extraction methods.

Extraction by steam distillation is the most common method and this yields 1 to 2% of a free-flowing, yellow to orange-yellow oil with an intensely sweet, floral, slightly woody aroma.

Solvent extraction is much less common and involves using a volatile solvent such as hexane. This results in the production of a fragrant wax-like substance known as an essence concrète, which is then washed with alcohol and concentrated into the essential oil. Solvent extraction is a much more technical and expensive process than steam distillation but yields a purer oil known as an absolute.

The essential oil and absolute are used extensively as a fragrance component in high-end perfumes, particularly of the floral type, such as 'Red Door' by Elizabeth Arden, 'Ysatis' by Givenchy and 'Chanel No. 5' by Chanel, as well as in men's fragrances, toiletry goods and cosmetics, including soaps, creams and lotions, and to some extent detergents. Both are also widely used as a flavouring in alcoholic and non-alcoholic beverages, including colas and other fizzy drinks, as well as dairy desserts, soft candy confectionery, chewing gum and baked goods.

The wood is soft, lightweight, averaging about 290 kgs per cubic meter (18 lbs per cubic ft), and has low natural resistance to rot and decay, making it unsuitable for most purposes although it can be pulped for paper or fibreboard.

Health use

The essential oil has a sedative or calming effect and is used in aromatherapy to reduce heart rate and blood pressure.


Grows naturally in moderately humid to very humid subtropical and tropical lowland to mid-elevation climates, generally in areas with annual lows of 16 to 25°C, annual highs of 26 to 35°C, annual rainfall of 1200 to 6000 mm and a dry season of 5 months or less, extending to 7 months with irrigation or groundwater.

Essential oil production is located mostly in humid tropical areas with a dry season of 2 months or less, as the trees in these areas tend to flower heavily and throughout the year, making it possible for continuous essential oil extraction.


New plants are usually started from seed, which germinate erratically. Germination is improved by first storing the seed under dry conditions for six to twelve months, then soaking them in hot water before sowing. Because the seed are tiny, they are collected by washing the pulp of mature fruit through a sieve under running water, then air-drying and storing them.

Treated seeds are then sown in deep containers with a free-draining potting mix, and the seedlings tended in a nursery until they are about 50 cm (1.6 ft) tall, after which they are planted-out. Care should be taken when transplanting not to damage the long taproot.

Performs best on deep, rich, free-draining clay, loam and sand soils of a moderately acid to moderately alkaline nature, generally with a pH of 5.0 to 8.0, and on sites with full to partial sun exposure. 

Cananga trees have good tolerance to season flooding but are intolerant of strong winds due to their brittle wood.

Under ideal conditions, a mature tree produces about 20 kg (44 lbs) of fresh flowers per year and, with an average oil content of 1.5%, yields 300 grams (10.6 ounces) of essential oil.

Problem features

Birds, bats and small animals are known to eat the fruit and disperse the seed. It is recorded as naturalised and as a weed in more than one country but there does not appear to be any record of it anywhere as a serious weed. It is assessed as a low weed risk species for Hawaii by the Hawaii Pacific Weed Risk Assessment (HPWRA) project.

The wood is brittle, which results in branches breaking off in strong winds and falling to the ground, potentially causing personal injury or damage to property.
