This lifeform is found in China. This non-native lifeform is now locally established in greater North America. This lifeform is only found domesticated.

Ginkgo tree was originally native to China, but is now grown widely as an ornamental.  This tree can be up to 120 feet tall.

Ginkgo Order (Ginkgoales) contains one family with but one  species. The Ginkgo was kept from going extinct by the Chinese who grew it in their monastery gardens. The  Gingko is an unusual Gymnosperm in that it has leaves. The Gingko is now grown widely in Europe and the United States as an ornamental. Some scientists place the Ginkgo in varying places in the taxonomy tree.

Gymnosperms are a group of trees and bushes usually characterized by needles and the production of cones to support the seeds. Most species are evergreen. (The actual technical definition has to do with the method of producing the seed.)

There are over 600 species of Gymnosperms known to science. The largest genus in this group in terms of species is the Pine genus with about 120 species. The second most common genus is the Podocarpus genus which is normally a more tropical group than the Pines.

Kartesz lists 135 species as growing in greater North America, including Hawaii, Puerto Rico, and the Virgin Islands.

Seed plants (Phylum Embryophyta) are generally grouped into one large phylum containing three major classes: the Gymnosperms, the Monocots, and the Dicots. (Some scientists separate the Gymnosperms into a separate phylum and refer to the remaining plants as flowering plants or Angiospermae.)

For North American counts of the number of species in each genus and family, the primary reference has been John T. Kartesz, author of A Synonymized Checklist of the Vascular Flora of the United States, Canada, and Greenland (1994). The geographical scope of his lists include, as part of greater North America, Hawaii, Alaska, Greenland, Puerto Rico, and the Virgin Islands.

Kartesz lists 21,757 species of vascular plants comprising the ferns, gymnosperms and flowering plants as being found in greater North America (including Alaska, Hawaii, Greenland, Puerto Rico and the Virgin Islands).

There are estimates within the scientific world that about half of the listed North American seed plants were originally native with the balance being comprised of Eurasian and tropical plants that have become established.

Plant kingdom contains a large variety of different organisms including mosses, ferns, and seed plants. Most plants manufacture their energy from sunlight and water. Identification of many species is difficult in that most individual plants have characteristics that have variables based on soil moisture, soil chemistry, and sunlight.

Because of the difficulty in learning and identifying different plant groups, specialists have emerged that study only a limited group of plants. These specialists revise the taxonomy and give us detailed descriptions and ranges of the various species.  Their results are published in technical journals and written with highly specialized words that apply to a specific group.

On the other hand, there are the nature publishers. These people and companies undertake the challenging task of trying to provide easy to use pictures and descriptions to identify those species.
