Ginkgo biloba  'Leather Green' is a very recent introduction from our good friend Charles Hunter, Iowa, U.S.A. It was selected because of the extraordinary size and shape of the leaves. 
 
Description - Ginkgo biloba ‘Leather Green’ produces very large leaves 20 cm – 25 cm across that are deeply cut, with additional serrations at the tips. It is very vigorous and from a graft produces it has produced in excess of 60 - 75 cm in a growing season. Therefore in 10 years this plant will exceed 6m in height and if trained as a tree its final size would correspond to that of a seed raised tree of the species.
