Stinky trees do great in urban environments
Cities plant stinky female gingkgoes—comparable to the odor of vomit or dirty socks—because they can withstand the pollution of dense urban areas for hundreds of years; many other trees barely last a decade. One surprising note: "It turns out the ginkgo, like some species of fish, can spontaneously change sex. This evolutionary adaptation allows ginkgoes to propagate when the sex ratio is imbalanced."
