Ginkgo biloba (it is sometimes incorrectly spelled Gingko) is a large, conical shaped deciduous tree.
The matt-green leaves are mid green, fan-shaped and bi-lobed, turning yellow before dropping in autumn.
This species has male and female forms and both are required if the female is to produce fruit in late summer. However it should be noted that a newly planted tree will take around 20 years to produce fruit.
The flowers are small and insignificant and the brown fruit has edible kernels, being much prized for its oil in parts of Asia.
It is very resistant to pollution and will grow well in cities, but keep in mind that it is initially a slow grower.
If you are not interested in the fruit it is worth planting a male tree and avoiding problems with fallen fruit around the base.
