On Tuesday September 25, the mayor of Nagasaki - accompanied by an extensive delegation op people - visited Leiden in context of the dear friendship between Nagasaki and Leiden, that exists since 2013. Since the group would pay a visit to the Japan Museum en the National Museum of Ethnology that same afternoon, the Hortus couldn't be left out.
Prefect Prof. Dr. Paul Kessler and former-hortulana Carla Teune gave a tour through the garden and informed the guests about all the special Japanese plants to be found there. Obviously they all paused in the Von Siebold memorial garden, that was dedicated to Philipp Franz von Siebold, who first started the plant exchange between The Netherlands and Japan. By doing so, the Japanese findings of von Siebold eventually found their way to Dutch ornamental horticulture.
In 2017 the mayor of Leiden visited Nagasaki and signed a declaration that officially sealed the dear friendship between the two cities. The declaration offers opportunities to further expand the network in Japan for the purpose of knowledge centers, museums and business life in Leiden.
