Flora Hills Notes
Common Names: Oud Tree, Agarwood Tree, Eaglewood, Aloeswood
Scientific Name: Aquilaria malaccensis (most widely known agarwood-producing species)
Origin: South and Southeast Asia – particularly India, Bangladesh, Myanmar, Malaysia, and Indonesia
The Oud tree belongs to the Thymelaeaceae family and refers to several species within the Aquilaria genus capable of producing agarwood, the dark aromatic resinous wood highly prized across the Middle East and Asia. Among them, Aquilaria malaccensis is one of the best known and commercially significant species.
Contrary to common belief, healthy Oud trees do not naturally contain fragrant agarwood throughout the trunk. The prized resin develops only when the tree experiences injury, fungal infection, or environmental stress, triggering a natural defense mechanism. Over time, affected wood darkens and becomes richly aromatic, producing the material known as oud or agarwood.
Globally, important agarwood-producing species include Aquilaria malaccensis, Aquilaria crassna, Aquilaria sinensis, Aquilaria subintegra, and Gyrinops species. In India and Kerala, cultivation mainly involves Aquilaria malaccensis and selected plantation varieties introduced for commercial and conservation purposes.
A mature Oud tree generally reaches 15–30 metres in height with a relatively straight trunk, smooth bark, and evergreen foliage. Under plantation conditions, trees are often managed and inoculated to encourage controlled resin formation.
While the tree does not produce edible fruits of nutritional importance, its value lies in the fragrant resin used for traditional incense, premium perfumes, essential oils, religious rituals, and medicinal systems. Oud oil remains among the most expensive natural fragrance ingredients in the world.
Environmentally, Oud trees contribute through carbon storage, forest restoration, shade, and biodiversity support, especially when cultivated within mixed tropical ecosystems rather than intensive monocultures. Because wild populations were heavily exploited for agarwood, several Aquilaria species are now protected and conservation-focused cultivation has become increasingly important.
At Flora Hills, the Oud tree represents mystery and patience. Its greatest treasure is not immediately visible but develops quietly over years through nature’s own processes—a reminder that some of the rarest values emerge slowly and under the right conditions.
