Cornus is a genus of 30-60 species[Note 1] of woody plants in the family Cornaceae. They are also called dogwoods or cornels. They have unique blossoms, berries, and bark.[3] Most of the Cornus are deciduous trees or shrubs. A few of these species are alsoperennial subshrubs. Some of the species are be evergreen. Many species in this genus have small flowers that are surrounded by an involucre. In the involucre, there are petal bracts. Some species have clusters of petal-bearing flowers. These flowers are native to temperate and boreal Eurasia and North America. China, Japan, and southeast United States have many of these native species.

There are many species of Cornus. Some common ones are the common dogwood Cornus sanguinea in Eurasia. In North America, there are many flowering dogwood (Cornus florida). In the Pacific and North America, there are many dogwood Cornus nuttallii. In east Asia, there is the Kousa dogwood Cornus kousa. In Canadian and Eurasian, there are dwarf cornels (or bunchberries): Cornus canadensis and Cornus suecica.

Dogwoods can be classified many ways. It is usually divided into 1 to 9 genera or subgenera.
