Ylang-ylang (IPA: /ˈiːlæŋˈʔiːlæŋ/) (ee-lang ee-lang) Cananga oorata, is a small flower of the cananga tree. It is a fast-growing tree that exceeds 5 meters per year and attains an average height of 12 meters. It grows in full or partial sun, and prefers the acidic soils of its native rainforest habitat. The leaves are long, smooth and glossy. The flower is greenish yellow (rarely pink), curly like a starfish, and yields a highly fragrant essential oil. A related species is Cananga fruticosa, which is a dwarf ylang-ylang that grows as small tree or compact shrub with highly scented flowers. Ylang-ylang has been cultivated in temperate climates under conservatory conditions. Its fruit are an important food item for birds, such as the Collared Imperial-pigeon, Purple-tailed Imperial-pigeon, Zoe's Imperial-pigeon, Superb Fruit-dove, Pink-spotted Fruit-dove, Coroneted Fruit-dove, Orange-bellied Fruit-dove, and Wompoo Fruit-dove (Frith et al. 1976).
