Cornus is a genus of about 3060 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. The bark of Cornus species is rich in tannins and has been used in traditional medicine as a substitute for quinine.

Cornus alba, the Siberian, white, or Red-Barked Dogwood is a large fast growing shrub or small tree. It is a popular ornamental used in landscaping, pot culture and the art of bonsai. Its most notable features include the masses of white fragrant flowers during spring and summer, the red stems in autumn through to late winter and the attractive foliage. It can grow from 1 to 3 metres high.
