The Dawes Arboretum

Common name: Troll ginkgo

Family: Ginkgoaceae (ginkgo family)

Distribution: Species native to e. China

Hardiness: USDA Zone 4

Life form: Deciduous tree

Comments: A deciduous dwarf, arguably the slowest and most compact of all ginkgo dwarf forms growing only about 1" per year. Troll is a witches'-broom found in Norway but introduced by Jeddeloh Nursery in Germany around 15 years ago. Leaves are typically fan shaped and representative of the species except for being about half the size. Light gray to brown stems are distinctly stubby and thickened. A male form meaning no smelly fruit. Good for Bonsai or rock gardens.
