Ginkgo biloba ‘Schönbrunn’ This female tree is located at Schloß Schönbrunn. Schönbrunn Palace was the main summer residence of the Habsburg rulers, located in Hietzing, Vienna, Austria. It was planted in 1781 and is the oldest Ginkgo in Austria. It was originally a male tree, which had a female scion grafted on to it. Plants of the female branches of this tree are propagated and distributed by J. Hahnl under the name Ginkgo biloba ‘Schönbrunn’. In addition, Josef Hahnl has selected a number of distinctive seedlings from seeds collected from this tress during 1993 – 2007. These selections have given rise to several peculiar haploid, diploid and tetraploid Ginkgo biloba cultivars (‘Adam’, ‘Ben’, ‘Curly Leaves’, ‘Dr. Faustus’, ‘Freak’, ‘Gretchen’, ‘Hop Sing’, ‘Hoss’, ‘Little Joe’, ‘Mephisto’).
