The Royal Botanic Gardens Peradeniya is a vast botanical garden located in the hill country of Sri Lanka, near the city of Kandy. Founded in 1821, it is one of the oldest and largest botanical gardens in Asia, covering an area of over 147 acres.

The gardens are home to a wide variety of flora and fauna, with over 4,000 species of plants, including orchids, spices, medicinal plants, and palm trees. There are also several themed gardens within the larger complex, such as the Royal Palm Avenue, the Spice Garden, and the Orchid House.

One of the main attractions of the Royal Botanic Gardens Peradeniya is the collection of tropical plants, including several rare and endangered species. Visitors can take guided tours of the gardens, which include stops at various points of interest, such as the giant Javan fig tree, the cannonball tree, and the Royal Botanic Gardens Peradeniya Herbarium, which houses a collection of over 100,000 dried plant specimens.

In addition to its natural beauty, the Royal Botanic Gardens Peradeniya is also a center for research and education in botany and horticulture. The gardens play a vital role in the conservation of Sri Lanka's flora and fauna, as well as in the promotion of sustainable agriculture and environmental awareness.
