Some do, but not the Princeton Sentry columnar ginkgo. The culprits are female ginkgo trees, which, in the fall, drop berries before they shed their leaves. These have a faint odor that has been likened to dirty gym socks. The Princeton Sentry ginkgo, however, is a male cultivar that does not have fruit. It does, on the other hand, have flowers with a pleasant scent, so if smells matter to you, the Princeton Sentry columnar ginkgo tree is a great option.
