The marking nut was formerly used in India to mark clothing for washing, because the mark remains visible after washing. In India, however, the species is better known under the name bhallataka and has many applications in traditional medicine, including for skin and rheumatic complaints. The fruits resemble those of the cashew and also consist of a red-orange accessory fruit and a black drupe. The accessory fruit is edible and tastes sweet, while the drupe is poisonous. The seed (nut) in the drupe is edible, but, like the cashew, must be carefully removed and prepared.
In nature, the tree grows in dry forests and can reach a height of up to 25 metres. The leaves are leathery and up to 15 cm in size. It is an easy grower that thrives in well-drained soil consisting of sand and potting soil (1:1) and in a sunny location. Pruning is possible with gloves, as the plant sap is poisonous. The species is dioecious, which means that a male and female plant are needed for fruiting.
Sowing description: The germinated seeds can be planted directly in a mixture of sand and potting soil (1:1). Ensure a light location and a temperature of 25-30°C for initial development.
