Lloyd’s Botanical Garden was established in 1878 when 40 acres (160,000 m2) of land was acquired at Darjeeling to form a botanic garden as a distant annexe of the Calcutta Botanical Garden. The land was provided by William Lloyd, in whose name the botanical garden has been named.
The Garden is situated just below the Eden Sanatorium in an open slope covering an area of about 40 acres, bound by Cart Road and Victoria Road on the North, by Jail Road and Hari Ghose Road on the south, by Eden sanatorium on the east and Victoria Road on the west. This Garden is one of the main attractions to the visitors to Darjeeling with a treasury of many rare and beautiful plants as well as patches of typical forest of tall Cryptomeria, Bucklandia and Alnus with thick mass of lianas and shrubby undergrowth. It is a favorite spot of recreation with vistas across some of the loveliest slopes, a paradise to the students and research workers in Botany and an eminent institution distributing the plants and seeds and specimens of temperate and sub-temperate Himalayas to different parts of the world.
The botanical garden has four gates. Gate No:1 ( Iron Gate or Loachnagar gate) is approachable from the taxi stand. The road is very steep but shorter than the other approaches. Vehicles can reach this gate, but there is no parking facility. Gate No:2 (Staff gate) can be approached from the Sadar Police Station. This path is through the settlements and is narrow and can be reached on foot only. The road will lead to the staff quarters and a flight of stairs will lead to Gate No:2.Approaching Gate No:2 on foot is comparatively easier than reaching other gates on foot. Gate No:3 (Chandmari gate) can be reached through Haro Ghose road which passes through the bazaar. Vehicles can reach this gate, but no parking is available. Gate No:4 (Victoria gate) is on the Victoria road and provides entry for visitors entering from the Western side.
The Darjeeling Botanical Garden preserves several species of bamboo, oak, magnolia, arisaema, cotoneaster, wild geranium, and rhododendron — forestnative plants of the Darjeeling Himalayan hill region, Sikkim region, and other neighbouring regions. Also, several exotic plants are preserved. The Cacti and Succulent collection of 150 species is displayed in the Conservatory. The collection of native Orchids from the Singalila Ridge in present-day Singalila National Park is rare and notable.
The Indian Botanical Garden Network’s Garden code ascribed for this garden is WB-DBG.
