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.
'Princeton Sentry' is an all-male cultivar typically growing at maturity to 40-50' with an upright, narrowly conical habit. Leaves turn a uniform golden yellow in autumn (spectacular when backlit by early morning or late afternoon sun) and persist for several weeks. When the leaves do drop, they drop rapidly, forming a golden carpet around the tree.
No serious insect or disease problems. Usually slow growing, with initial growth being somewhat sparse.
Excellent choice for a variety of uses, including lawn tree, street tree or shade tree. Also effective in city parks and near commercial buildings.
