Name that Plant – using its biological nomenclature could be a quiz show for avid gardeners, but only experts might win. Botanists, horticulturalists, garden historians, and master gardeners have an understanding of how and why many plants are named. To the rest of us, it may seem puzzling.
Plants are given a binomial or two names, a genus and a species. The species is the basic unit of plant classification. Variations, hybrids, and cultivars are all subdivisions of the species. A similar group of species forms the genus. The genus designates the group of closely related plants. It is estimated that there are a quarter of a million plant species on earth.
The Swedish botanist, Carolus Linnaeus (1707-1778) developed a system to give each plant a genus name and a species name. This eventually became the International Code of Botanical Nomenclature in 1906. His system had such flexibility that it could accommodate the many modifications to plants in later years.

The names are usually written in Latin, printed in italics, with the genus names first and capitalized. The species name is next, written in lower case letters. Plants are named for people, places, mythological characters, associations with animals, body parts, and much more. The Missouri Botanical Garden has a research website, The Unseen Garden, where one can find information about plants and projects from all over the world.
Hybrid species of plants are called nothospecies. They are named using either a hybrid formula of their parents’ names, or a binomial with a multiplication sign. There are also the many common names that have no rules and which may change from region to region or vary at one time or another.
