Ginkgo biloba

During the Jurassic era, forests of ginkgo-like trees blanketed the ground with their thick leaves. Now, fossils of those leaves are the only evidence we have of relatives of the ginkgo. Until 1690, it was thought by Europeans that fossils were the only evidence of ginkgos overall. That year, the German botanist Engelbert Kaempfer saw the tree in a Japanese temple garden, and the tree was spotted again in China the next year. Samples of the tree were collected, and news of this beautiful plant spread. The tree was given the scientific name Ginkgo biloba, due to the split nature of the leaves the tree produces on its long shoots. As only one type of leaf was collected, the fan-like shape of its other leaf type was undocumented for some time. Eventually, ginkgos became very popular as urban street trees due to their hardiness and beauty – with one caveat. The ginkgo is one of many types of trees that have separate male and female individuals. While the males produce showers of pollen, this is considered manageable when compared to the female's stinking fruit. Although edible if cleaned and processed, ginkgo fruit that has ripened and fallen to the ground can have a scent comparable to cat urine. For this reason, landscapers try to avoid planting female trees. Smithsonian Gardens has a single female tree, as an example.
