- Description
-
Ginkgo biloba is a deciduous conifer (a true gymnosperm) that can mature to a whopping 100' tall. A living fossil, it is the only surviving member of a group of ancient plants believed to have inhabited the earth over 150 million years ago. (Is it possible that the vile smell of the fruit attracted dinosaurs to consume and later discharge the berries, helping spread the seeds?) Is it also popular for use in bonsai and can be kept artificially small for centuries.
An upright, columnar, male selection of Ginkgo that has been a proven performer here in North Carolina, ‘Bryson City’ Ginkgo was brought from China and planted in 1941 by Mary Bryson Tipton. Mrs. Tipton, a missionary, was forced to leave when Japan invaded China. Bryson City was named after Mrs. Tipton’s family. The original tree grows in downtown Bryson City.
Ethnobotany: The extract of the ginkgo leaves has been used pharmaceutically, but mainly used as a memory-enhancer and an anti-vertigo treatment. Gingko nuts are considered to have aphrodisiac qualities.
Seasons of Interest:
Foliage: Fall, yellow
Wildlife Value: Ginkgos have no wildlife value. It is over-planted in today’s cities which decreases wildlife diversity in the urban environment.
Insects, Diseases and Other Problems: No serious insect or disease problems. Can be allergenic; for those sensitive, it produces a skin dermatitis similar to poison ivy. This tree is deer-resistant.

- Leaf Description:
- Ginkgos have distinctive two-lobed, somewhat leathery, fan-shaped, rich green leaves with diverging (almost parallel) veins. Leaves turn bright yellow gold in fall. Ginkgo trees are commonly called maidenhair trees in reference to the resemblance of their fan-shaped leaves to maidenhair fern leaflets (pinnae). Ginkgoes have the curious habit, in mid-fall, of dropping all of their leaves virtually at one time, usually following a heavy rainstorm. One autumn day, the bright foliage will be intact on the graceful spire-like tree; then, the next morning, the ground underneath the bare branches will be carpeted with its vivid leaves.
