I looked up information about Ginkgo and found out that the ginkgo is a living fossil, with fossils recognizably related to modern ginkgo from the Permian, dating back 270 million years. The closest living relatives are the cycads, which share with the extant G. biloba the characteristic of motile sperm. Fossils attributable to the genus Ginkgo first appeared in the Early Jurassic, and the genus diversified and spread throughout Laurasia during the middle Jurassic and by the Palaeocene, only a few Ginkgo species remained in the Northern Hemisphere. At the end of the Pliocene, Ginkgo fossils disappeared from the fossil record everywhere except in a small area of central China, where the modern species survived.
Ginkgo evolved in an era before flowering plants, when ferns, cycads, and cycadeoids dominated disturbed streamside environments, forming a low, open, shrubby canopy. The large seeds of Ginkgo and its habit of "bolting"—growing to a height of 10 metres (33 ft) before elongating its side branches—may be adaptations to such an environment. (edited from Wikipedia)
I planted a small Ginkgo tree in a planter on my deck. Family questioned my sanity by mentioning how tall it grows but I'm hoping that my great grand children will be around to see in planted in the backyard and thriving in the sunshine!
Now, I'm happy to offer three designs in Thermofax Screens that I've created with Ginkgo Leaves as the inspiration. They come taped and ready in three different sized frames: Small = 3 3/4" x 5", Medium = 5" x 8", Large = 8" x 10 3/4". Check them out here: http://fabricimagery.com/category/nature/
