Ginkgo biloba belongs to the Cinkgoceae family and is the only species of its genus. This deciduous tree is native to China where it grows in the wild to a height of 30 m (100 ft). When young, the ginkgo is cone-shaped, slowly spreading as it gets older. The leaves are fan-shaped with parallel veins; they are pale green in spring, turning a beautiful golden yellow in autumn. The ginkgo is a robust tree that will grow in sun and partial shade. It is frost-resistant and tolerates urban pollution and wind. Unwanted shoots and branches can be cut back in late winter or spring. To ensure the production of seeds male and female trees are necessary. The femaledevelop into plum-like fruits. These can be harvested in mid-autumn when the flesh is removed and the seeds stored in a refrigerator for sowing in spring. Ginkgo can also be raised from softwood cuttings taken between spring and early summer.
