Trichilia emetica is a magnificent evergreen hardwood. The lovely glossy, deep green, drooping foliage forms a rounded crown, creating dense, dark shade. With its low branching habit and sturdy single trunk the Natal mahogany has long been one of our most popular indigenous ornamental trees. When the flowers begin to appear from December, the sweet scent can be enjoyed on warm summer evenings while those beautiful jewels of the garden, the sunbirds, can be observed delighting in the generous amounts of nectar. The bright red and black seeds are enjoyed by a number of bird species while a variety of butterfly larvae feed on this tree. In the wild, where antelope, monkeys and giraffe forage on the fruit and foliage, Trichilia emetica is an accurate indicator of palatable grass species.

|Growth Habit|| |
Trichilia emetica is found along streams and rivers as well as in woodland, coastal forest, montane forest and savannah.
The dark grey to brown bark is smooth but can become rougher as the tree ages.
The Natal mahogany has dark green compound leaves with each pair of leaflets alternate or sub-opposite with a single leaflet at the tip. The upper surface of the glossy leaves is smooth while the underside is covered with dense, felt like hairs.
The small, creamy- green, sweet scented, trumpet shaped flowers are carried in dense axillary sprays from August to November.
The furry, grey-green fruit appears in bunches from December to April. Each fruit is divided into three valves that carry 3-6 seeds which are released when it ripens and bursts open.
The black seeds are almost entirely enveloped by a bright red aril and look similar to a lucky bean. It should be noted that the outer coat of the seed is poisonous.
Trichilia emetica is found in sub-Saharan Africa from Senegal to the Red sea, throughout East and Central Africa and from the Congo to South Africa.
The Natal mahogany prefers a sunny or semi-shaded position, plenty of compost and a moderate amount of water.

Trichilia emetica has a wide variety of uses. The skinned seeds are edible. When they are soaked in water or ground, they enhance the flavour of spinach dishes, while a sweet milky liquid is extracted from the arils. The oil that is extracted from the seed kernels and husks is excellent for soap and candle making as well as being used as a superior furniture oil. The oil is also widely used in cosmetics and as a food preservative. The powdered bark of this remarkable tree is used as an emetic and is effective for the treatment of rheumatism.
