Where plants and trees from around the world seen at home Hakgala Botanical Gardens, just 10km away from Nuwara Eliya City. Hakgala
is one of the places one visits as an essential part of a pleasant journey in
the famous hill resort of Nuwara Eliya. The site is legendary. It was once the pleasure garden of Ravana of the Ramayana epic and according to many, it was one of the places where the beautiful Sitha was hidden by the demon king. The present Botanic Gardens were founded in 1860 by the eminent British botanist Dr. G.H.K. Thwaites who was superintendent of the more famous gardens at Peradeniya, near Kandy.

It was the site initially for experiments with cinchona whose bark yielded quinine, esteemed as a tonic and febrifuge. Quinine at that time was widely used as a specific for malaria. This was perhaps the reason for the popularity of and tonic in these parts - quinine being the principle ingredient of tonic water.
The cool, equable climate of the hakgala area, whose mean temperature is around 60 degrees Fahrenheit, encouraged the introduction of suitable temperate zone plants, both ornamental and useful. These included conifers and cedars from Australia, Bermuda and Japan, and cypresses from the Himalayas, china and as far a field as Persia, Mexico and California. New Caledonia gave Hakgala a special variety of pines and there are specimens of this genus from the canary Island as well.
An English oak, introduced around 1890, commemorates the "hearts of oak" of Britain's vaunted sea power, and there is a good-looking specimen of the camphor tree, whose habitat is usually in regions above 12,000m.
