Maidenhair-Tree (Ginkgo)
Maidenhair-Tree Genus Details
The leaves of Ginkgo trees are deciduous and fan shaped. The fruit is similar in size to a plum and orange-yellow in color when ripe. Fruit from the female trees has a very foul odor when it is opened and reveals a large white seed. The tree is often planted as an ornamental in the United States. The species, Ginkgo biloba, is the only one of its family in the world and is known to be a living fossil. Fossils indicate that many other species existed in the past and Ginkgo biloba may have also been extinct had it not been planted in temple gardens in the Orient. It is also known as the "maidenhair tree" because its leaves resemble that of a fern.
