Commonly known as the maidenhair tree, the ginkgo is unusual in having no close relations. Ginkgos are large trees, reaching over 100ft, with long, erratic branches. The leaves are unique among seed plants: they are fan-shaped, with veins extending to the end but never interlocking.

The tree is famous for being tough and tenacious. Ginkgo trees were among the few living things still alive after the atomic bomb was dropped on Hiroshima.
