Ginkgo biloba

Accession Number
The alpha-numeric value assigned to a plant when it is added to the living collection as a way of identifying it.
Accession Date
The year the plant’s accession number was assigned.
Common Name
The non-scientific name for the plant.
Scientific Name
The scientific name describes the species of an organism. The first word is the plant's scientific genus and the second is the specific epithet. This two-word binomial is sometimes followed by other taxonomic descriptors, including subspecies (denoted by "ssp."), variety (denoted by "var."), form (denoted by "f." or "forma"), and cultivar (denoted by single quotation marks).
Plant Family
The family to which the plant belongs.
Propagation Material
The first part (material code) describes the material used to create the plant. The most common codes are "SD" (seed), "EX" (existing plant), "PT" (plant), "CT" (cutting), "SC" (scion), "SG" (seedling), and "GR" (graft). The second part describes the lineage the plant is derived from. The last part describes the year of propagation.
Collection Data
The first part indicates provenance (place or source of origin) using a letter code ("W" = wild, "G" = garden, "Z" = indirect wild, "U" = uncertain). The second part lists the plant source. For wild-collected material, the collector, collection number, and country are given.
The location of the plant on the landscape.

Ginkgo biloba
SD - LINEAGE 1113-89
W - China - Del Tredici, P.

This ginkgo was collected, in 1989, from one of the few presumed wild populations of this species in China.

In the early 20th century, American and European botanists believed that the ginkgo, while common in cultivation Cultivation: The act of caring for or raising plants. , was extinct in the wild. These distinctive trees were often seen in gardens and around temples in China, Japan, and Korea. Many of the cultivated specimens were hundreds of years old. Given the prominence of these trees, it was curious that field botanists had never reported seeing them growing in the wild.

Then, in 1915, a prolific American plant collector named Frank Meyer reported that he had visited a mountainous valley in southeastern China where he saw ginkgos growing freely. The trees were so abundant that neighboring communities cut them for firewood. When the Arnold Arboretum’s first director, Charles Sprague Sargent, described Meyer’s discovery the following year, he suggested that the trees might have escaped from a cultivated source. The discovery was nevertheless exciting. “It is exceedingly interesting, whatever may be the history of these trees, to find that there is at least one place in China where the Ginkgo grows in the woods and reproduces itself spontaneously Spontaneous plant: A plant that grows and reproduces freely without human care or intent. ,” Sargent wrote.

More than 60 years later, in 1989, Arboretum researcher Peter Del Tredici visited the same location in northwestern Zhejiang Province: a mountain called Tian Mu Shan. Over the intervening years, Chinese botanists had continued studying the ginkgos and advocated for their protection with a nature preserve. Del Tredici worked with two Chinese colleagues—Ling Hsieh (of the Zhejiang Forestry Department) and Yang Guang (of the Nanjing Botanical Garden)—to inventory ginkgos within the reserve. Del Tredici also collected seed from the ginkgos, which he brought back to the Arnold Arboretum. This tree, planted on the southern slope of Peters Hill, was grown from Del Tredici’s collections.

More recently, genetic evidence has been brought to bear on the question of whether the ginkgos at Tian Mu Shan are, in fact, wild. In 2008, a Chinese researcher named Wei Gong, then at Zhejiang University, worked with colleagues to study wild-type ginkgo populations. Their research confirmed that the Tian Mu Shan ginkgos had the level of genetic diversity that would be expected for a wild population. Three additional populations in southwestern China had similar levels of diversity.

Del Tredici has also visited and collected seeds from ginkgos in two other wild-type populations in Guizhou Province. More than forty ginkgos at the Arboretum originated from his efforts. These trees form the core of the Arboretum’s ginkgo collection, which is nationally accredited by the Plant Collections Network. The collection is an essential resource for conservation and research.

About Our Collection

Fun Facts

  • Researchers have discovered fossils of ginkgo relatives that are more than 270 million years old.

  • The fleshy outer layer of ginkgo seeds contains the same pungent chemical (butyric acid) that characterizes the smell of human vomit. At Tian Mu Shan, researchers have observed an omnivorous carnivore known as the palm civet eating and dispersing the seeds.

  • The largest ginkgo in the world grows outside of Li Jiawan, Guizhuo Province, China. Its trunk diameter is over fifteen feet at ground level. It is at least four thousand years old.

  • In 1937, a Japanese botanist named Tamaki Shimamura discovered that ginkgo pollen—unlike the pollen of all other living seed plants (except cycads)—produces motile sperm.
