The Botanical Garden hosted a Day of Open Heart event on August 6, 2014. A ginkgo sapling, grown from seeds delivered June 2013, was planted by a 12-year-old. A memorial ceremony for victims of the tragedy of the atomic bombing of Hiroshima was also held. The Botanical Garden website stated: "We are confident that our objectives and activities of the international competition 'Adopt a Tree!' miraculously coincide with the meaning of Green Legacy Hiroshima. We have a common world, and we should love it! Save this world and preserve life on our planet; we can make it happen all together!"

In a second trial, ginkgo, jujube, hackberry, and camphor seeds were delivered. The seeds started to germinate and are in good health. Dr. Iurii Naumtsev, director of the botanical garden, personally planted them. He also gave an interview on this occasion to a regional news agency, saying, “It is truly a joy and an honor for us. Pass on our sincere thanks to our colleagues from the Hiroshima Botanical Garden for their help in the shipment." He also wrote to GLH, saying, "I feel as if we were little messengers of peace in the family. Thank you for such a miracle.”
