Baobab is the common name of a genus containing eight species of trees, native to Madagascar ，having six species), mainland Africa and Australia (one species in each).This tree is the National Tree of Madagascar.

Other common names include boab, boaboa, bottle tree,the tree of life, upside-down tree, and monkey bread tree. The species reach heights of 5 to 30 metres (16 to 98 ft) and trunk diameters of 7 to 11 metres (23 to 36 ft). Its trunk can hold up to 120,000 litres of water. For most of the year, the tree is leafless, and looks very much like it has its roots sticking up in the air.

The trees are long-lived, but just how long is disputed. The owners of Sunland Farm in Limpopo, South Africa have built a pub called "The Big Baobab Pub" inside the hollow trunk of the 22 metres (72 ft) high tree. The tree is 47 m (155 ft) in circumference, and is said to have been carbon dated at over 6,000 years old.
