### Identification The Ginkgo is a "living fossil" with a silhouette unlike any other. Reaching heights of 100 feet, young trees appear spindly and pyramidal, while elders develop massive, irregular crowns. The field mark that never fails is the fan-shaped leaf: a bright, leathery green blade with a distinct central notch (*biloba*) and unique parallel veins that fork but never cross. In autumn, these leaves transform into a uniform, luminous saffron gold. Look closely at the branches; you’ll notice "short spurs"—knobby little pegs where clusters of leaves and fruit emerge, contrasting with the grey, deeply furrowed, corky bark.
### Habitat & Range While its wild ancestors once blanketed the Northern Hemisphere during the Jurassic, the Ginkgo's natural range is now restricted to the remote valleys of Zhejiang province, China. However, it is a champion of the "urban ecosystem." Due to its incredible resistance to pollution, salt, and pests, it is a staple of city streets from New York to Tokyo. It thrives in well-drained soils and full sun, often outlasting every other tree in the concrete jungle.
### Behaviour As a dioecious species, Ginkgos are strictly male or female. In spring, males produce dangling, catkin-like pollen cones, while females grow pairs of ovules on long stalks. The most dramatic "behaviour" occurs in late autumn; unlike other trees that shed leaves over weeks, a Ginkgo may drop its entire golden canopy in a single day following a hard frost, creating a sudden, brilliant carpet. Be warned: the female’s fallen seeds contain butyric acid, which emits a potent scent often compared to rancid butter or gym socks.
### Diet The Ginkgo is a master of photosynthesis. It "feeds" by capturing solar energy through its broad leaves, converting water and carbon dioxide into complex sugars. Its deep, tenacious root system is exceptionally efficient at mining minerals from even the most compacted, nutrient-poor urban soils.
### Fascinating Fact The Ginkgo is the ultimate survivor. Six Ginkgo trees were growing within a mile of the 1945 Hiroshima atomic blast; while almost all other life was incinerated, these trees survived the heat and radiation. They regrew their leaves shortly after and are still standing, healthy and vibrant, today.
