The origins of the Botanic Gardens date as far back as 1371 when King Wickramabahu III ascended the throne and kept court at Peradeniya near Mahaweli river. This was followed by King Kirti Sri and King Rajadhi Rajasinghe. A temple was built on this location by King Wimala Dharma, but it was destroyed by the British when they were given control over the Kingdom of Kandy. Thereafter, the groundwork for a botanical garden was formed by Alexandar Moon in 1821. The Botanical Garden at Peradeniya was formally established in 1843 with plants brought from Kew Garden, Slave Island, Colombo, and the Kalutara Garden in Kalutara. The Royal Botanic Garden, Peradeniya was made more independent and expanded under George Gardner as superintendent in 1844. On his death in 1849 George Henry Kendrick Thwaites became superintendent. He served until 1879, when he was succeeded by Henry Trimen, who served until 1895. The Garden came under the administration of the Department of Agriculture when it was established in 1912.
