The Ginkgo, is the world's oldest living species of tree, the sole survivor of the Ginkgolaceae family whose fossil records date back to when dinosaurs roamed the earth, around 125-220 million years ago. Today Ginkgo Biloba is known as the living fossil. It was, in fact, thought to be extinct in the wild until rediscovered in the 17th century in eastern China. Great bonsai tree potential. Easy to grow and maintain because of its adaptability and resistance. If left to grow naturally, the Maidenhair tree will grow from about 80 to 100 feet tall. These trees can live a long time, some over 600 years. The bark is delicate, be careful. Pruning scars do not heal, so avoid making large scars. Protect well against frost, its roots have a high moisture content, and are easily destroyed by frost when exposed to the elements in a shallow bonsai container. They have characteristic fan-shaped leaves that are usually bi-lobed and leathery. Leaves in Spring are a light green, but will suddenly turn a pure dazzling yellow in the Fall, remaining for awhile on the tree, then suddenly dropping virtually all off at the same time. Ginkgos will take about 20 years of growth before they start to reproduce. The flowers of the trees will appear in Spring, with male trees producing cones and females the fruits. Hardiness zones 3-8, (-10øC/15øF, -37øC/-35øF) in Winter. Ginkgo tolerates most soil, including compacted, and alkaline. Needs a fair amount of water during growth. Its main requirement is adequate drainage. Prefers full sun, but in very sunny areas partly shadow is better. Maximum light is necessary for good Autumn color. Very young trees may need some shelter in Midsummer.
