Why are female ginkgo trees less popular than male trees for street and garden planting?

Female ginkgo trees are less popular for street and garden planting primarily due to the characteristics of their seeds. When the fleshy outer layer of the mature seed decays, it emits a very disagreeable odor, which is often compared to that of rancid butter. Additionally, these fallen seeds can create a slipping hazard on paved surfaces, making them less desirable for urban landscapes.12

Because ginkgo trees are dioecious—meaning male and female reproductive structures are borne on separate trees—landscapers and gardeners typically prefer to plant male trees to avoid these issues.132
