Baobab (Adansonia)

baobab tree

The baobab can grow up to 30m (98 ft) tall and can live for several thousand years. The Glencoe baobab, a specimen of A. digitata in Limpopo Province, South Africa, was considered to be the largest living individual, with a maximum circumference of 47 m (154 ft) and a diameter of about 15.9 m (52 ft).

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 is accurate, and 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 the oldest known angiosperm tree.
