Dr. Orland E. White, Blandy Experimental first Director, began collecting ginkgo
seeds in 1929 from a single “mother tree” on the University of Virginia Grounds in Charlottesville. After these seeds germinated, Dr. White’s students planted over 600 ginkgo saplings to determine the sex ratio of this tree. Most plants are both male and female, but like holly, persimmon, and other species, ginkgo is dioecious, meaning a tree is usually male or female, but not both. Dr. White hypothesized the sex ratio would be
1:1. He did not live long enough to find out if he was right, but of the 301 trees that survived to maturity and for which gender could be determined, 157 were female and 144 were male. Statistically speaking, this does not deviate significantly from1:1. "

A-bombed Ginkgo tree in Hiroshima, Japan This Ginkgo situated near a temple about 1130 m away from the hypocenter appeared to bud after the blast (the temple itself was destroyed). The temple-site in Housenbou was smaller after the war and they considered transplanting or cutting down the Ginkgo to rebuild the temple. In 1994 it was decided to leave it there and adjust the temple to it, so now the main building has stairs in front divided into left-and right hand sides, protecting the Ginkgo inside this U-shape. Engraved on it "No more Hiroshima" and people's prayers for peace. This tree has thus become an international symbol. Estimated planting 1850, 15 m.
Location: 3-3 Tera-machi, Naka-ku. Near Nishihongan-ji and Zensho-ji.
