Ginkgo is an Asiatic genus of hardy deciduous trees represented notably by one species, Ginkgo biloba, often called Maidenhair tree because of its attractive foliage that resembles in form that of the popular Maidenhair fern (Adiantum).

Ginkgo biloba tree grows to 35 feet (10.6m) tall with a characteristic diagonally upright form and flowers in loose catkins. Ginkgo is native to northern China and Japan; it is the sole survivor of a family of trees widespread in early geologic times.

The Ginkgo is much used as a street or park tree or for planting as a specimen where a picturesque effect is desired. It is hardy in northern regions and because of the rather leathery texture of the leaves practically free from insects pests and disease.

The Ginkgo is commonly a slow grower, about 1 foot per year, but under ideal conditions can grow up to 3 feet (.9m) each year.

Ginkgo is easily propagated from seed, by layer, and cuttings
