Botanical Gardens, Sri Lanka.

Apart from the natural verdure, there are several gardens and parks. The tradition of cultivating land for aesthetic purposes goes back more than 2000 years to the time of the ancient kings. The ruins at Anuradhapura and subsequent royal cities have left remnants of grounds that are among the earliest and best landscaped in Asia. The more recent parks make rewarding walks not only for the plant lover but also for the bird enthusiast. The main parks are;Hakgala Botanic Garden, The Royal Botanic Gardens at Peradeniya and Henarathgoda Botanic Garden.
