Ginkgos were a rare species, but this cultivation not only kept the trees alive, but also spread them throughout Eastern Asia. They were eventually introduced to Europe and North America, where their hardiness has made Ginkgos a popular choice for landscaping and urban planning. They are truly one-of-a-kind trees.
