History & Significance

Henarathgoda's story begins in 1825 when Governor Edward Barnes planted an extensive garden on the Kelani River banks. It truly took root in 1876, established specifically to introduce rubber to Sri Lanka under British rule. Here, the first rubber seedlings from Brazil—imported via Kew Gardens—were nurtured, blossoming into Asia's inaugural rubber trees and kickstarting the island's rubber industry. Seeds from these pioneers spread to South India, Malaysia, and Myanmar. Today, operated by Sri Lanka's Department of National Botanic Gardens, it stands as one of six national botanical gardens, preserving these historic plantings as national monuments. The nearby old Henarathgoda Railway Station once served scientists researching rubber, adding another layer to its legacy.
