Elaeocarpus ganitrus grows in the area from the Gangetic plain in the foothills of the Himalayas to South-East Asia, Nepal, Indonesia, New Guinea to Australia, Guam, and Hawaii. Rudraksha seeds are covered by an outer husk of blue colour when fully ripe, and for this reason are also known as blueberry beads. The blue colour is not derived from pigment but is structural. It is an evergreen tree that grows quickly. The rudraksha tree starts bearing fruit in three to four years. As the tree matures, the roots buttress rising up narrowly near the trunk and radiating out along the surface of the ground.
