The Associated Press has an article on Ginkgo biloba trees (a.k.a. maidenhair trees), and the fact that some cities are removing them due to odor problems. Landscapers normally prevent this problem by planting only male trees – that’s right, there are male and female ginkgos, and it’s the females who drop the sticky, stinky seed pots – but the approach has flaws. For one, if there are no female trees in the area, then sometimes some of the males will convert. And sometimes, nurseries have inadvertently sold females as males.(Link courtesy of Robin Rosetta.)
