America burned Japan's first gift of cherry trees. All 2,000 of them, on President Taft's direct order. The 1910 shipment arrived in DC crawling with insects and nematodes. Agriculture inspectors condemned the lot, Taft signed off on the bonfire, and the State Department braced for a diplomatic disaster. Tokyo's mayor, Yukio Ozaki, responded by sending 3,020 more, grafted from the famous grove along the Arakawa River. Those trees have spent a century paying the friendship back. Four days after Pearl Harbor, vandals chopped down four of them. Park officials renamed the survivors "Oriental" cherry trees for the rest of the war to protect them from axes. Then came the twist. By 1952 the original Arakawa grove in Tokyo, the parent stock, had nearly died from wartime neglect. Japan asked Washington for help. The Park Service shipped budwood from DC's trees back across the Pacific and restored the grove that created them. When a flood wiped out more Japanese trees in 1982, horticulturists took 800 fresh cuttings from the Tidal Basin. These 250 new trees solve a real problem too. The Tidal Basin is sinking, and a $133 million seawall rebuild forced crews to rip out roughly 150 trees. Japan offered replacements before anyone asked, timed to America's 250th birthday. So the genetics run in a loop. Tokyo's grove seeded Washington's. Washington's saved Tokyo's. The saplings going in this spring descend from both. 114 years of diplomacy, running on grafted branches.
