Ginkgo biloba is the last surviving species of Ginkgophyta. These long-lived plants evolved during the Permian period 250 million years ago. Ginkgo trees are called living fossils, because they strong resemble ancient remains preserved in the geologic record.
The popularity of ornamental ginkgo trees in Asia has led to their widespread cultivation.
Ginkgos can live for hundreds of years. Their height may be up to 30 meters and a trunk diameter up to 2 meters.
