Long Garden is predominantly a rose garden containing sixteen rose beds. This garden is four hundred and thirty feet in length and is enclosed by walls that are about twelve feet high. It is often known as the Purdha garden. Besides popular and heritage varieties of roses like Rose Ice Berg, Rose Summer Snow, Rose Okla Homa, Rose Lousiana the beds are margined with Dahlia, Marigold, Salvia, Gazania, Oxalis, Ranunculus and Iris. The central pavement has a red sandstone pergola which is covered with Rose creepers, Patrea, Bougainvilleas and Grape vines.

On both sides of the pergola, rows of sandstone elephant trunks depict Indian features in the architecture of Long Garden.

The twelve feet high walls are covered with creepers like Flame vine, Trumpet vine, Adenocalymma (Lassan bel) and Jasmine that add fragrance to the garden. Along the walls, one can see the China Orange trees or Kumquats that have been planted. Long Garden is connecting link between Central Lawn and Circular Garden.

Sweet fragrance from Jasmine, Roses, and sounds of wind chimes and wate falling from the fountain at circular garden next to it also make it a Sensory Garden.
