All Baobabs are deciduous trees ranging in height from 5 to 20 meters. The Baobab tree is a strange looking tree that grows in low-lying areas in Africa and Australia. It can grow to enormous sizes and carbon dating indicates that they may live to be 3,000 years old. One ancient hollow Baobab tree in Zimbabwe is so large that up to 40 people can shelter inside its trunk. Various Baobabs have been used as a shop, a prison, a house, a storage barn and a bus shelter. The tree is certainly very different from any other. The trunk is smooth and shiny, not at all like the bark of other trees, and it is pinkish grey or sometimes copper coloured.
Adansonia trees produce faint growth rings, probably annually, but they are not reliable for aging specimens, because they are difficult to count and may fade away as the wood ages. Radiocarbon dating has provided data on a few individuals. A specimen of A. digitata known as Grootboom was dated and found to be at least 1275 years old, making it one of the oldest known angiosperm trees.
