Only one species of Ginkgo exists: a deciduous, dioecious tree from southern China that is extinct in the wild. Its relatives grew on Earth up to 150 million years ago. Male flowers are more conspicuous than female ones. The fan-shaped leaves are yellowish green and turn golden in the fall, lasting for several weeks. Ginkgo tolerates pollution, making it a good urban tree.
