Ginkgo tree

Ginkgo biloba, commonly known as the Ginkgo tree or maidenhair tree, is a species of tree native to China. It is the only surviving member of the ancient order Ginkgoales, which dates back over 270 million years. The Ginkgo tree is renowned for its unique fan-shaped leaves and is often cultivated for its beauty as a street or garden tree. It is also valued for its purported medicinal properties and has been used in traditional Chinese medicine for millennia.

Description

The Ginkgo tree can grow to a height of 20–35 meters (66–115 feet). Its leaves are distinctive, being bilobed and fan-shaped, with veins radiating out into the leaf blade. These leaves turn a bright yellow in the fall, making the tree particularly attractive during this season. Ginkgo trees are dioecious, meaning that individual trees are either male or female. The female trees produce seeds that have a fleshy outer layer, which, when ripe, emits an unpleasant odor.

Distribution and Habitat

Originally from China, the Ginkgo tree has been planted around the world in temperate climates. It is highly resilient and can tolerate a wide range of environmental conditions, including pollution and confined soil spaces, which makes it a popular choice for urban landscaping.

Ornamental

Conservation
