GLH partners around the world





Green Legacy Hiroshima has been established to safeguard and spread worldwide the seeds and saplings of Hiroshima’s A-Bomb survivor trees. It is hoped that many partners will join this initiative and become active ambassadors in their countries of Hiroshima, its peace message and its green legacy.

In early November 2022, GLH had the pleasure to host plant scientists and botanic garden experts from renowned institutions in the United States, who visited Hiroshima to observe and study the Hibakujumoku firsthand. The delegation included Ari Novy from the San Diego Botanic Garden (and a member of GLH Committee), Todd Michael and Wolfgang Busch from the Salk Institute for Biological Studies, Nicole Cavender from the Huntington Botanical Gardens, and Philip Douglas from the Denver Botanic Gardens.

GLH Regional Seed Hubs

San Diego Botanic Garden (SDBG) in San Diego, California, the College of Agriculture, Food & Rural Enterprise (CAFRE) in Northern Ireland, and the Universidad Austral de Chile (UACH) in Chile

We are delighted that the SDBG, CAFRE, and UACH have agreed to become GLH regional seed hubs. We hope their help will facilitate sharing A-bombed tree seeds with more partners in the United States, United Kingdom, and Latin America.

Dr. Eoin Lettice appeared on Irish national television to tell the story of the seeds of survivor Ginkgo biloba trees in Cork, Ireland and demonstrate the hope they symbolize. Green Legacy Hiroshima’s relationship with Dr. Lettice and the University College Cork Arboretum has allowed survivor seeds to be planted and germinate 10,000 km away from Hiroshima.
