Today walking along the main drag I saw a pile of small yellowish fruit at the base of one of the doomed trees planted in concrete boxes along the way. (Doomed because it's the main drag and exhaust fumes kill the city trees there on a regular basis.) City trees don't usually run to fruit-- and then I saw it was a gingko.
Now this is amazing, firstly because no one in their right mind would plant a female gingko tree anywhere, and secondly because the dog-shit smell of the fruit (the reason you don't plant female trees) was absent. I wondered if they were edible, so came home and googled. That doesn't inspire me to go back for the fruit. Also this piece of lore: "Only the female trees bear fruit, and they need to be in proximity to a male ginko to make the nuts." I see no other gingkos around, so I fancy all there is there is toxic flesh.
Because otherwise I'm sure the passing Koreans would have grabbed the lot.
