Ginkgo biloba 'Pendula' is thought be many to be a study in wishful thinking. Many selections bearing the 'Pendula' name are anything but a weeping form. Clearly multiple clones exist under this cultivar name. In most cases, plants grow in tree form with widely ascending branching with weeping branchlets.
[New Ornamentals Society] Stiffly weeping forming inverted umbrella over time. Some branches may be irregular and horizontal or nodding at best. It is more of a curiosity than a truly beautiful plant in most cases.
It is unclear if our modern clones are same as the original. The cultivar name has been in the nursery trade since the 1860s and thought to have originated in Belgium.
