The argan tree is an endemic tree of Morocco, 8 to 10 m high, very resistant to the drought of the region and which lives between 150 and 200 years.

It is distinguished by a specific silhouette: the top of the tree is broad and rounded, the trunk is short and gnarled, with intertwined shapes and twigs full of thorns; the small dark green leaves are lanceolate, persistent and tough. The hermaphroditic flowers are greenish-yellow in colour, and thanks to its powerful root system, it maintains the soil by maintaining its fertility and protects it from erosion due to rain and wind. 828,000 hectares of Moroccan territory are occupied by the argan tree, which is the second largest cultivated tree species in Morocco after the holm oak.
