The Botanical Gardens add great educational and recreational value to Puducherry. The gate leading to the garden is reminiscent of French architecture and it stands out from its immediate surroundings because it is smack in the middle of the old Tamil town. The Botanical Gardens were laid out in 1826 in ornate French style, with pruned trees, beautiful flower beds and gravel lined paths and fountains.
The French introduced many exotic plants from all over the world, many of which thrived. The sprawling 22 acres garden houses more than 1500 species of plants with placards indicating the species, common name and interesting information like the uses of the tree, amount of oxygen generated and its medicinal value; this could well qualify as one of the best botanical gardens in South India.
