Cornus alba (red-barked, white or Siberian dogwood) is a species of flowering plant in the family Cornaceae, native to Siberia, northern China and Korea. It is a large suckering shrub that can be grown as a small tree. As a popular ornamental used in landscaping its notable features include the red stems in fall (autumn) through late winter, the brightest winter bark of any cornus;[1] and the variegated foliage in some cultivars, such as C. alba 'elegantissima', in which the discreet flat whitish flower clusters are almost lost in the variegated texture and dappled light. C. alba can grow to 3 m (10 ft) high, but variegated forms are less vigorous. For the brightest winter bark, young shoots are encouraged by cutting to the ground some older stems at the end of the winter, before leaves are open.
The plant is extremely hardy, to USDA Zone 3.
The following cultivars have gained the Royal Horticultural Society's Award of Garden Merit:-
- 'Aurea'[2] (yellow leaves)
- 'Elegantissima'[3] (deep red stems and small white flowers)
- 'Sibirica'[4] (2.5 m (8 ft 2 in), brilliant red stems, cream flowers)
- 'Spaethii'[5] (variegated leaves with yellow margins)
