Founded in London in 1804 as The Horticultural Society of London (Prince Albert changed it to Royal Horticultural Society in 1861, which is the current title). With over 200 years of strong influence in the field of horticulture around the world, it popularized gardening through continuous researches, collection, publications, exhibitions and shows. The society earned its reputation and influence, and raised the status of English gardens to a national level with its passion for plant collecting and through horticultural researches, exhibitions and design shows.

Index Seminum

Index Seminum, meaning ‘List of Seeds’ is a non-commercial seed exchanging program that allows arboretums, botanical gardens, and research institutes to autonomously exchange various seeds based on the Convention on Biological Diversity (CBD). The arboretum joined the program in 1977, and has the largest variety of plant species in Korea with over 15,800 taxa as of 2017.
