Banyan Tree

A single tree that can spread across 2 hectares using aerial roots/Plants

The banyan (Ficus benghalensis) is a fig tree famous for its aerial prop roots that grow down from branches to the ground, where they thicken into trunk-like pillars. Over time, a single tree can spread across enormous areas, creating the appearance of a small forest. The Great Banyan in the Acharya Jagadish Chandra Bose Indian Botanic Garden near Kolkata has a canopy circumference of about 486 meters and covers roughly 1.89 hectares, making it the widest tree in the world. The national tree of India, the banyan plays a central role in Hindu, Buddhist, and Jain traditions as a symbol of eternal life and interconnection.
