Ginkgo biloba 'Kazimierz Wielki (KORSZUN)  is a new cultivar originating from Poland, bred at the University of Life Sciences in Poznań by Stanisława Korszun. It is a quick growing cultivar with long and fairly thick shoots that hang down, which give it a slighly weeping appearence, but overall, it has an upright habit. One of its intresting characteristics are that it produces large leaves often up to 20 cm across.  It grows quickly, up to 10 m in height which makes it suited to planting in parks and larger gardens. It is expected to have good autumn colour.
