The Baobab, Adansonia digitata, (also known as the upside down tree, and monkey bread tree) is a drought-tolerant tree common to much of sub-Saharan Africa. The species reach heights of between 5–25 m (exceptionally 30 m) tall, and up to 7 m (exceptionally 11 m) in trunk diameter. They are noted for storing water inside the swollen trunk, with the capacity to store up to 120,000 liters of water to endure the harsh drought conditions particular to the regions of Africa near the Saharan, Kalahari and Namib deserts. This is a very versatile tree and the young leaves, which can either be palmate or simple, are often picked and eaten as form of spinach. The leaves are also dried as a coarser tea cut. To encourage leaf growth large fields of young baobabs are grown for their leaves alone. Senegal is one of the largest commercial producers of baobab leaf tea.
