Ginkgo biloba ‘St. Cloud’ (syn. Ginkgo biloba ‘Horizontalis’) but now accepted as a  distinct cultivar in its own right. This male cultivar originally came from the Jardin Axel Kahn (now the Albert Kahn Museum and Garden) in St. Cloud-sur-saine, Bois de Boulogne, Paris, France. It was a Japanese garden made by the idealistic Banker, Albert Kahn, between 1895 and 1910. 
 
This is a good example of how one named plant miraculously becomes a different named cultivar. A Mr. Meyer took cuttings from a Ginkgo biloba ‘Horizontalis’ growing in the garden, successfully propagating it he described it (or should that be named it?) as ‘St. Cloud’. Romain Billon writes that ‘in 1960 this variety continued to be marketed as St. Cloud in the United States’. Hence an interesting example of  Ginkgo biloba ‘Horizontalis’ became  Ginkgo biloba ‘St. Cloud’.
