- Description
-
Ginkgo is a long-lived, woody, deciduous, prehistoric tree in the Ginkgoaceae (ginkgo) family. It is native to south-central and southeast China and is often called a living fossil because the ginkgo has existed for hundreds of millions of years.
While it tolerates a variety of soil textures and pH, ginkgo needs a site in full sun and good drainage to thrive. Avoid wet soils. It can grow 50 to 80 feet tall and 30 to 40 feet wide. Fruits from female trees are messy and have foul smelling fleshy seeds, so planting male trees is often preferable.
This tree’s pyramidal shape and unique fan shaped leaves, which turn yellow in the fall, bring a beautiful quality of light as the sun filters through its canopy.
The ginkgo tree is tolerant of drought, heat, air pollution, and is moderately salt tolerant, which makes it an excellent choice for urban settings, streetscapes, recreational play areas, and walkways. It is also deer resistant. Its sculptural form makes it popular for use in bonsai.
Insects, Diseases, and Other Plant Problems: May cause contact dermatitis.

- As a gymnosperm, Ginkgo does not produce fruit but its seeds (only on female trees) are plumlike, yellow-orange, the outer, fleshy pulp foul-smelling when ripe, the inner wall hard, smooth, and cream colored. When the seeds fall to the ground they can be quite messy. Most of the ornamental ginkgoes in the United States are male.

- Flower Description:
- Ginkgos are gymnosperms and do not produce "flowers" however they are dioecious with separate male and female trees. Male plants produce small pollen cones with sporophylls. Female plants produce ovules at the end of a stalk. Fertilization occurs via motile sperm, as in cycads, ferns, mosses, and algae.
