It is the first and only international garden show in the tropics to bring together top international award-winning landscape and garden designers, florists and horticulturists from around the world, who are invited to the Festival to work alongside Singapore’s own talented horticulturists. 

The festival is organised by the National Parks Board of Singapore, in partnership with the Agri-Food and Veterinary Authority of Singapore (AVA), the Orchid Society of South East Asia (Singapore), the Singapore Gardening Society and the Singapore Tourism Board (STB).

The Singapore Garden Festival was first held in 1885 under the name The Flower Show at the Singapore Botanic Gardens and, in 2006, was restarted and renamed as the Singapore Garden Festival. The 2020 exhibition was postponed because of the COVID-19 pandemic and will take place in 2022.

In 2014, the Singapore Garden Festival was awarded the 2014 International Garden Tourism – Achievement of The Year Award which was presented at the Gardens Without Limits Conference in Metz, France. The event held in 2016 was also recognized by Guinness World Records as the World’s Largest Floral Chandelier.
