Noteworthy Characteristics

Ginkgo biloba is a deciduous conifer (a true gymnosperm) that matures to 100' tall. It is the only surviving member of a group of ancient plants believed to have inhabited the earth up to 150 million years ago. It features distinctive two-lobed, somewhat leathery, fan-shaped, rich green leaves with diverging (almost parallel) veins. Leaves turn bright yellow in fall. Ginkgo trees are commonly called maidenhair trees in reference to the resemblance of their fan-shaped leaves to maidenhair fern leaflets (pinnae). Ginkgos are dioecious (separate male and female trees). Nurseries typically sell only male trees (fruitless), because female trees produce seeds encased in fleshy, fruit-like coverings which, at maturity in autumn, are messy and emit a noxious, foul odor upon falling to the ground and splitting open.

‘Mariken’ is a dwarf, low-spreading, somewhat weeping/pendulous male form that grows very slowly to only 2’ tall by 2’ wide over the first 10 years. It may eventually reach 3’ tall by 8’ wide. It was reportedly cultivated from a witches broom found on a species tree. Small green leaves turn a uniform golden yellow in autumn.

Problems
