A place known for the largest number of commercial flower nurseries, Kalimpong nurseries specialize in the cultivation of exotic flowers. These are then exported to different parts of the country. There are numerous nurseries across town for you to enjoy, some of which are famous for housing exotic cactus. Cactus is often dismissed as a dry, desert plant, with not enough aesthetic value. But you'll be surprised to come across different varieties of cactus here that are found all across the world, all beautiful in their unique way.
