Sexuality of ginkgo is very mysterious. In botanical garden in Bratislava (slovakia), there are 5 ginkgo trees, all producing seeds. Therefore, no male tree around, but seeds are fertilized. I thought there would be a male branch on a female tree, but employees of the botanical garden told me that nobody had not grafted the trees. Any explanations?
In Bratislava, there are few male ginkgo trees capable of fertilizing those females.
Male trees will not often turn into females. Moreover they will not produce as many seeds then as the female trees.

I have lived in a house in Oak Park, IL for 16 years. It had a young Ginkgo tree when I moved in that I would estimate was about 10 years old. I love the tree and was delighted it was not a female. This year for the first time it produced a few of the seeds - not as many as a normal female tree, but it clearly has changed sex. I don't think it was a graft, though I am unsure of this.
