Ginkgo biloba, also called maidenhair, is a broadleaf, deciduous tree. While it loses its leaves in winter, it is classified as a conifer and is dioecious, meaning that some trees are male while others are female. Native to China, ginkgo biloba trees, broadly speaking, will grow well in planting zones 4 through 9.The gingko biloba's uniquely fan-shaped leaves start out green but change to golden-yellow in the fall. Before the whole leaf turns golden, there is sometimes a stage during which the leaf is two-toned, with separate bands of gold and green. The common name "maidenhair" was inspired by the fan shape of the leaves, which reminds people of the maidenhair fern (Adiantum spp.). The bark on older specimens of the tree becomes deeply furrowed.
