Royal Botanic Gardens, Peradeniya
The history of the Royal Botanic Gardens dates as far back as 1371 when King Wickramabahu III ascended the thrown and kept court at Peradeniya near Mahaweli river. Later, in the reign of King Kirti Sri from 1747 - 1780 King Rajadhi Rajasinghe resided therein, where a temporary residence was erected for him.
A vihare and dagaba were built in the reign of King Wimala Dhamma which was improved by Kind Rajadhi Rajasinghe. The vihare and dogaba were destroyed by the English when they occupied Kandy. The famous historical battle of Gannoruwa between Rajasinghe II and the Portuguese was fought on the Northern side of the river. A priest resided here till the Gardens were formed by Mr Alexandar Moon in 1821 six years after the final conquest of the Kandyan Kingdom.
In 1810 under the advice of Sir Joseph Banks a garden named Kew was opened in Slave island and Mr William Kerr was appointed as its Superintendent. In 1813 the garden was moved to Kalutara for the reception of economic plants which could be cultivated there on a larger scale than was possible at Slave island. Kerr died in 1814 and under the rule of his successor Mr Alexander Moon this Garden was finally moved to Peradeniya in 1821 as it was found to be favorable and better adapted for the proposed Botanic establishment. The transfer of exotics from the Kalutara Garden was made by successive Superintendents at least up to 1843.
During Moon's superintendent the opening of the Royal Botanic Gardens, Peradeniya, can be said to have commenced though at first only the South West portion of the Gardens was cleared and opened and it was mostly planted with cinnamon and coffee. Moon published his "Catalogue of Ceylon Plants" in 1824 in which was given the Botanical and native names of 1, 127 plants, indigenous to the island. After the appointment of Mr George Gardner in 1844 the institution started upon its more active independent and useful existence that it has since maintained. Only 40 acres of the 147 acres were in cultivation when Gardener took charge and the chief use made of the land was to grow jak, coconuts and vegetables for sale by the Government Agent in Kandy. Gardner effected many important improvements in the condition of the Gardens but his chief work was the exploration of the country for the collection and preparation of its flora. He died at Nuwara Eliya in 1849 and was succeeded by Dr Thwaites who for over 30 years maintained the Gardens in a high state of efficiency, added largely to our knowledge of the flora of the Colony and gave the establishment its worldwide reputation. Botanic Gardens at Hakgala was established in 1861 for introduction of Cinchona into the island and in 1876 Gampaha (Henarathgoda) Botanic Garden was started for the introduction of Rubber.
Thwaites was succeeded by Dr Henry Trimen, under whose rule and capable management the beauty and usefulness of the Gardens were very considerably advanced. He established the Museum of Economic Botany, opened branch Gardens at Badulla and Anuradhapura and began the publication of his work, "The Flora of Ceylon" which however was finished by Sir Joseph D. Hooker after Trimen's death in 1896. In 1896 Trimen was succeeded by Dr J.C. Willis and from that date a new extension of scientific work took place. In the early years work was mainly directed towards the introduction and acclimatization of useful and ornamental plants but in later years activities developed towards Economic, Botany and Agriculture and led to the development of the Department of Agriculture in 1912. Mr H.F. Macmillan who was appointed Curator in 1895, was made the Superintendent of Botanic Gardens in 1912 and Mr T.H. Parsons the Curator in 1914. During Macmillan's superintendent the Gardens were improved and extended and his great work "a Hand Book of Tropical Planting and Gardening" was published. Macmillan retired in 1925 and Mr T.H. Parsons continued as curator till 1945.
