This garden was laid out in 1847 by the Marquis of Tweedale and is spread over 55 acres. Lush green well maintained lawns, rare tree species (like the cork tree which is probably the only such tree in India, the paper bark tree and the monkey puzzle tree - monkeys cannot climb this tree), a 20 million year old fossilized tree, an Italian-style garden bordering a clear pool, a vast variety of flowering bushes and plants in myriad hues (exotic and ornamental), fern house with a vast range of ferns and orchids, are some of the many highlights of this garden. A flower show along with an exhibition of rare plant species is held every year in the month of May at this garden. The Garden is maintained by the Horticulture Department of the Government of Tamil Nadu and has a very wide variety of plants that include different types of roses, imported shrubs, rare flowering plants etc.
