GINKGO BILOBA: Morphology |
|
|
A Ginkgo biloba tree can reach 30 or 40 meters height and a spread of 8 meters. The trunk can become about 3 or 4 meters wide in diameter. It is straight columnar and sparingly branched. Young trees have usually a central trunk, pyramidal in shape, with regular, lateral, ascending, asymmetrical branching . The bark is brown and rough. It fissures rough furrows with the age. The male tree usually has a slim column form and is slightly longer, the female tree has a wider crown and a more spread out form. |

The Ginkgo biloba tree has long and short branches growing at right angles. A short branch may become a long branch and the tip of a long branch may change into a short branch. That's why older trees may have a more irregular form. The leaves grow alternate on the long branches during spring. On the ends of short, lateral shoots they grow very slowly in clusters and produce a long shoot with scattered leaves after a number of years. |

The leaves of this tree are interesting and unique from any other tree. They are fan-shaped, leathery and smooth. They are often deeply grooved in the middle of the leaf, producing two distinct lobes, hence the name Ginkgo biloba (two lobes). The leaves have a venation pattern that is open dichotomous; the veins fork in pairs from the base of the leaf, and are not cross-connected. They are bright green during the summer, turning gold before dropping in the fall. However, leaves fall quickly and the fall color show is short! |
