A ginkgo is a unique tree, known for its fan-shaped leaves and ancient lineage; Ginkgo biloba is the only surviving species of its kind. Imagine it as the last member of a rock band that was super popular ages ago. It's a living fossil, meaning it's changed very little over millions of years. These trees are hardy and can live for a very long time. They're often planted in cities because they're resistant to pollution.
