Ginkgo Biloba: Unveiling the Ancient Majesty
Ginkgo biloba, known by various names such as Salisburia adiantifolia, Icho, Fossil Tree, Maidenhair Tree, Ginkgo, or Gingko, belongs to the esteemed Ginkgoaceae family of plants. This large deciduous tree has a fascinating history and unique characteristics that make it a captivating presence in the natural world.
Origin and Discovery: Tracing the Ancient Roots
Native to China, Ginkgo biloba is a living relic that dates back millions of years. Fossil evidence reveals that Ginkgo biloba is the only surviving member of its genus, with a lineage that can be traced back an astonishing 270 million years. This remarkable longevity is a testament to its resilience and ability to withstand the test of time.
The name “Ginkgo biloba” has its origins in Japanese, with “Gin Kyo” meaning silver apricot. The spelling “Ginkgo” was introduced by Engelbert Kaempfer, a German naturalist who explored various regions, including Japan, during the late 17th century. The species was later published by Carl Linnaeus in 1771. The specific epithet “biloba” comes from Latin, with “bis” meaning two and “loba” referring to lobed, aptly describing the distinctive shape of its leaves.
Description and Features: A Tapestry of Beauty and Resilience
Ginkgo biloba is a large tree that can reach heights of up to 35 meters or 115 feet. It typically possesses an angular crown and erratic branches, creating an intriguing silhouette against the sky. The branches grow with leaves arranged in a regular pattern along their length. The fan-shaped leaves of Ginkgo biloba are notable for their unique structure, featuring veins that radiate or fork outwards. They are characterized by notched edges and can grow up to 12 centimeters or nearly 5 inches in width. During the autumn season, these leaves transform into a brilliant shade of bright yellow, creating a stunning display of fall foliage.
Reproduction and Fruit: Gendered Beauty
Ginkgo biloba is a dioecious species, meaning there are separate male and female trees. Male trees produce small pollen cones, while female trees bear two ovules at the end of their stalks. Once pollinated, the female trees develop seeds. The fruit of Ginkgo biloba is dull yellow in color and emits an unpleasant fragrance. In fact, Ginkgo biloba was once thought to be extinct in the wild until it was discovered growing in two locations in China: Zhejiang and Tianmushan.
Cultivation of Ginkgo biloba: Nurturing the Living Fossil
Growing Ginkgo biloba requires attention to specific cultivation practices to ensure its successful development. Here are some key considerations:
- Sunlight: Ginkgo biloba thrives in sunny conditions, making it ideal for areas with ample sunlight exposure.
- Soil: This majestic tree demonstrates versatility when it comes to soil types, tolerating most varieties. However, it prefers well-drained soil to prevent waterlogging.
- Moisture: While Ginkgo biloba appreciates moisture, it is crucial to ensure proper drainage to avoid waterlogged conditions.
- Propagation: Ginkgo biloba can be propagated through seeds or semi-hardwood cuttings, providing options for plant enthusiasts.
- Maintenance and Pest Resistance: Ginkgo biloba is a low-maintenance tree that is generally disease-free and pest-resistant, further highlighting its resilience and adaptability.

In local cuisine, particularly in China, Ginkgo biloba plays a role in various dishes. The nuts of Ginkgo biloba are utilized in congee, a traditional rice porridge often served during weddings or as part of a dish known as Buddha’s delight. In Japan, Ginkgo seeds are incorporated into chawanmushi, a savory egg custard dish. It is important to note that consuming Ginkgo seeds in large quantities over extended periods may lead to MPN (Micturition-Prompting Factor) poisoning.

Ginkgo biloba has been utilized in traditional Chinese medicine since the 5th century and continues to hold a significant place in herbal medicine practices today. In contemporary times, Ginkgo biloba is marketed in health food stores for its potential cognitive benefits and its association with Alzheimer’s disease.
