Irvingia gabonensis is a large African forest tree grown mainly for its edible fruit and fatty seeds (dika nuts). It is grown in the humid tropics, and its key to success is patience, since trees can take years to fruit and seed germination is poor.

About
Irvingia gabonensis is a species of African trees in the genus Irvingia, sometimes known by the common names wild mango, African mango, or bush mango. They bear edible mango-like fruits, and are especially valued for their fat- and protein-rich nuts.
How to grow it
In the past, 90% of African bush mango products were harvested from scattered, wild trees. African bush mango trees were not cultivated initially, because it was believed, that it took up to 15 years for a tree to bear fruit. Although they were not artificially planted, their occurrence was high because they were also rarely harvested for timber. In a plantation using marcots (air-layering plants), flower production was observed within two to four years after planting.
Germination from seeds is low and when they are not handled appropriately, most fail. The seeds are mostly extracted by breaking fruits by hand.
Where it grows
Irvingia gabonensis is indigenous to the humid forest zone from the northern tip of Angola, including Congo, DR Congo, Cameroon, Nigeria, Ivory Coast and south-western Uganda. Since 2009, the Gabonese government has prohibited logging of the andok tree until 2034.
Uses
The fruits are often eaten fresh by humans and other mammals such as monkeys, gorillas, elephants and many more. As it is naturally and predominantly found in parts of Africa, it has been popularly called African mango. The fruits are processed into jelly, jam, juice and sometimes even wine. The pulp has also been used to prepare black dye for cloth coloration.
