Dogwood (Cornus) – ornamental woody shrub – 17 cm pot – 45 cm tall

No, the Siberian Dogwood (Cornus alba 'Sibirica') is a deciduous shrub: its leaves fall in autumn, after taking on beautiful yellow to orange hues. It is precisely at this moment that the plant reveals its main asset: very bright coral red stems that remain decorative all winter until the return of spring. Far from being a flaw, this winter bareness is the signature of this shrub, particularly striking after a white frost or under the snow. In the garden, it then constitutes a strong visual landmark in a dormant bed.

Siberian dogwood has what is considered a moderate growth rate, of around 30 to 50 cm per year in good soil and exposure conditions. Without pruning, it can reach 2 to 3 metres in height and spread within a few years, forming a dense shrubby clump. If you cut it back regularly in March to stimulate colourful new shoots, the plant remains lower and more compact, at around 1 to 1.5 metres. In moist, sunny soil, growth is significantly faster than in dry, shaded soil.

The color of the stems of the Cornus alba 'Sibirica' is most intense on the young shoots of the current year. To ensure an abundant growth of these shoots, perform severe coppice pruning every year or every two years, in late February or early March, before bud break. Cut the old stems 20 to 30 cm above the ground: the plant regrows with remarkable vigor and the new shoots will display a much more intense red than the older stems. Sunlight also plays a role: a full-sun location enhances the coloration. Finally, regularly moist soil supports vigorous growth that promotes beautiful shoots.

Yes, Siberian Dogwood is an excellent choice for a natural, rustic, or semi-trimmed hedge. Its dense foliage during the growing season provides good privacy from May to October, and its ornamental red stems maintain strong visual appeal all 'winter. It tolerates annual pruning very well, allowing it to be kept at the desired height. Its spring flowers and bluish-white autumn berries also make it a nectar-rich hedge that supports wildlife. For a continuous, full hedge, use several plants spaced 60 to 80 cm apart, depending on the pack size chosen.

The Cornus alba 'Sibirica' is one of the few ornamental shrubs that will tolerate heavy, cool, even slightly wet or clay soils. It thrives in garden areas with poor drainage where many other plants refuse to establish. Ideally, the soil should be cool, moist, and rich in organic matter. It tolerates neutral to slightly acidic or alkaline soils, with no particular requirements. However, avoid very dry and stony soils, where growth will be stunted and flowering reduced. A compost amendment at planting gives it an excellent start.

Siberian Dogwood is one of the hardiest ornamental shrubs available in garden centers. Native to the cold regions of Central Asia and Siberia, Cornus alba 'Sibirica' easily withstands temperatures well below -20°C. It requires no winter protection, even in regions with severe continental or mountain climates. Paradoxically, it looks its best in the cold: frost and snow accentuate the brilliance of its fiery red stems. It is therefore an absolutely safe choice for all French gardens, from the plains to areas of moderate altitude.

Siberian dogwood lends itself to many garden combinations. In winter, its red stems create a striking contrast with the yellow-green stems of the Cornus sericea 'Flaviramea'; pair the two for a spectacular two-tone effect. By the water, it pairs perfectly with evergreen grasses such as sedges or miscanthus. In a mixed border, it complements large-leaved hydrangeas, spiraeas, and shrub roses. To highlight its white autumn berries, plant it next to a Cotinus coggygria with purple leaves.
