Siberian Dogwood

Cornus alba

Cornus alba, the Siberian or Red-Barked Dogwood, is a large suckering shrub that can be grown as a small tree. It is from the family Cornaceae. As a popular ornamental used in landscaping it notable features include the red stems in fall through late winter, the brightest winter bark of any ''Cornus'' and the variegated foliage in some cultivars, such as ''C. alba 'elesantissima' '', in which the discreet flat whitish flower clusters are almost lost in the variegated texture and dappoled light. Variegated forms are less vigorous; ''C. alba'' can grow to 3 metres high, but for the clearest winter bark, young shoots need to be encouraged by cutting to the ground some older stems at the end of the winter, before leaves are open; the rough bark of older stems is not a notable feature.

The plant is extremely hardy, to USDA Zone 3.
