Have you ever heard about 250 years old ‘The Great Banyan Tree’, in the AJC Bose Botanical Garden, Kolkata, India? The vastness of the tree is almost the size of a Manhattan city block with 80 ft high and an area of 14,500 square ft. The number of roots and prop-roots of this banyan tree has surpassed 3600 and it has been a real botanical wonder since ages.
