The maximum observed rooting depth of a Boscia albitrunca plant in the Kalahari desert was 68 meters. This tree species typically reaches heights of up to 10 meters, although it often remains smaller in size. The tree’s crown is unusual, often flattened underneath due to browsing by antelope and other grazers that reach the leaves.
It was discovered in the central Kalahari in 1974 and had an amazing root structure, with roots reaching as deep as 68 meters. This extraordinary depth makes it the plant with the deepest known roots to date.
