Ylang-ylang (Unona)

Description

The genus Unona is in the family Annonaceae in the major group Angiosperms (Flowering plants). Cananga odorata, known as the cananga tree (Indonesian: kenanga, Filipino: ilang-ilang), is a tropical tree that is native to Indonesia, Malaysia, and the Philippines. It is valued for the perfume extracted from its flowers, called ylang-ylang (a name also sometimes used for the tree itself), which is an essential oil used in aromatherapy. The tree is also called the fragrant cananga, Macassar-oil plant, or perfume tree. Its traditional Polynesian names include Mata‘oi (Cook Islands), Mohokoi (Tonga), Moso‘oi (Samoa), Moto‘oi (Hawaii), and Mokosoi, Mokasoi or Mokohoi (Fiji). The ylang-ylang vine (Artabotrys odoratissimus) and climbing ylang-ylang (Artabotrys hexapetalus) are woody, evergreen climbing plants in the same family. Artabotrys odoratissimus is also a source of perfume. Cananga odorata is a fast-growing tree of the custard apple family Annonaceae. Its growth exceeds 5 m (16 ft) per year, and it attains an average height of 12 m (39 ft) in an ideal climate. The evergreen leaves are smooth and glossy, oval, pointed and with wavy margins, and 13–20 cm (5–8 in) long. The flower is drooping, long-stalked, with six narrow, greenish-yellow (rarely pink) petals, rather like a sea star in appearance, and yields a highly fragrant essential oil. Cananga odorata var. fruticosa, dwarf ylang-ylang, grows as small tree or compact shrub with highly scented flowers. The plant is native to the Philippines, Malaysia and Indonesia, and is commonly grown in Madagascar, Polynesia, Melanesia, Micronesia and the Comoros islands. It grows in full or partial sun, and prefers the acidic soils of its native rainforest habitat. Ylang-ylang has been cultivated in temperate climates under conservatory conditions. The essential oil is used in aromatherapy. It is believed to relieve high blood pressure, normalize sebum secretion for skin problems, and is considered to be an aphrodisiac. According to Margaret Mead, it was used as such by South Pacific natives such as the Samoan Islanders where she did much of her research. The oil from ylang-ylang is widely used in perfumery for oriental- or floral-themed perfumes (such as Chanel No. 5). Ylang-ylang blends well with most floral, fruit and wood scents. In Indonesia, ylang-ylang flowers are spread on the bed of newlywed couples. In the Philippines, its flowers, together with the flowers of the sampaguita, are strung into a necklace (lei) and worn by women and used to adorn religious images. Ylang-ylang's essential oil makes up 29% of the Comoros' annual export (1998). Ylang-ylang is a common flavoring in Madagascar for ice cream.
