You may recognize the scientific name Ginkgo biloba, even if you haven’t seen the tree it belongs to. Ginkgo extracts can be found in nutritional supplements, shampoos, energy drinks, and many other products.
Right now is the perfect time to look for the plant itself—its fan-shaped leaves turn bright yellow in fall, and female ginkgo trees drop their smelly fruits.
The ginkgo is one of our most unusual trees. Here’s why:
1. It’s a prehistoric relic. To find the earliest plant that looked like a ginkgo, you’d have to go back over 200 million years. More modern-looking ginkgoes were widespread during the Jurassic period. However, they’d died back to just one region of China by the time the first people walked the planet.
But these days, the ginkgo can once more be found all over the world, because…
2. It tolerates cities well. People like planting it in urban areas because pests generally avoid it, and it’s tolerant of pollution, storms, and compacted soil. You’ll find the ginkgo lining streets all over the world, from Tokyo to New York City.
3. It has unique leaves. The ginkgo is also a popular city tree because of its elegant foliage—its leaves are wedge-shaped, with veins fanning out from a central point. In autumn, they turn a brilliant yellow.
Unlike maples and other colorful fall trees, ginkgoes often drop their leaves within a short period; sometimes most of them fall during a single day. Keep an eye out for this tumbling golden display or watch a short video of it on our Facebook page.
4. It has stinky fruit. In autumn, you may smell a ginkgo before you see one. The female plants produce fruit whose stench has been likened to rotten cheese. This smell is so pungent that many plant nurseries will only sell male plants, which don’t make fruit.
Some scientists suggest that this odor once attracted mammals (or even dinosaurs) that liked spoiled meat. These now-extinct creatures would have eaten the fruit and spread the seeds.
Is there a beautiful—and maybe stinky—ginkgo tree in your neighborhood?

fyi, Gingko was the featured tree in the “Species Spotlight” in a Mass. DCR Citizen Forester electronic newsletter (see http://www.mass.gov/eea/docs/dcr/stewardship/forestry/urban/citizen-forester/cf2013-feb.pdf)
The “nuts” (really seeds) inside Gingko fruits are edible. Here’s what I said about that (excerpted from the Species Spotlight mentioned above):
Ginkgo Edible Notes
By Russ Cohen
The ―nuts (really seeds) inside the yellow fruits (which are produced by the female trees only) are edible and are used in Chinese cooking. The challenge is in gathering and processing the nuts. First, the smell of the fruits surrounding the nuts is truly repulsive (I liken it to dog vomit). It is essential to remove every bit of the fruit off the shell containing the nut – and it is best to do this outside to keep the repulsive smell out of your kitchen.
Secondly, some folks get dermatitis from handling the fruit and nuts with bare hands, so it is best to wear impervious gloves (like rubber gloves) when handling them. That said – if you are up to this challenge, the nuts (i.e., seeds) inside the shells are starchy and tasty, and can be prepared a variety of ways – one simple preparation is to mix the shelled nuts in teriyaki sauce, then spear them with a skinny wooden skewer, and then grill the skewered nuts over a hibachi.
