Dogwood is a tree comprised of about 30 to 50 species of predominantly deciduous woody plants which grow as shrubs or trees. However, some species grow as herbaceous perennial plants and a few evergreen woody species. It has been considered one of the most interesting type of trees. Dogwoods belong to the family of Cornaceae, which is divided into up to nine subgenera or genera.

Most of dogwood’s varieties are flowering trees. The Cornus or Cornels species is easily recognised by its yellow and white clustered flowers. The four main classifications of Cornus can be found in different countries, including the Blackfruit Cornel of California, the Chinese Cornel of China, the Japanese Cornel of Japan, and Cornelian-cherry of Mediterranean. Several varieties of Cornus bear fruits can be eaten.
