Siberian dogwood Cornus alba 'Siberian Pearls'
ABOUT
Siberian Pearls, a cultivated variety of the Red Twig Dogwood, is a deciduous shrub known for its stunning winter appeal. During the growing season, its leaves are green with a somewhat ovate shape, often displaying modest white flowers that give way to clusters of white, pearl-like berries in the fall and winter. These berries are quite attractive to birds and wildlife. The foliage can turn shades of reddish-purple in the autumn, providing aesthetic interest through the changing seasons. What makes the Siberian Pearls particularly noted is its striking red branches that become intensely colorful in the winter months after the leaves have fallen. These vivid red stems create a stark and beautiful contrast against snowy landscapes or grey winter skies, making it a popular choice for gardeners looking to add winter color to their gardens. The plant can spread by suckers and contribute to a dense thicket if not managed properly.

- Water
The Tatarian Dogwood, commonly known as Cornus alba 'Siberian Pearls', should be watered deeply and thoroughly to ensure that the water reaches the deep roots. During the growing season, watering once a week with approximately 1 to 1.5 gallons of water is recommended, depending on the weather conditions. In hot and dry periods, increase the frequency to twice a week. During the dormant season in winter, reduce watering to every two weeks or less, depending on soil moisture. Always check the soil moisture before watering and avoid overwatering, as this can lead to root rot.
- Light
The Tatarian Dogwood thrives best in full sun to partial shade conditions. Ideally, planting it in a spot that gets at least 4 to 6 hours of direct sunlight daily is beneficial for the health and flowering of the plant. However, it can also tolerate and adapt to light shaded areas, making it versatile in terms of lighting placement in a garden.
- Temperature
For the Tatarian Dogwood, temperatures between 50°F and 75°F are ideal for its growth and development. While it can survive temperatures as low as -30°F during dormancy in winter and withstand occasional spikes above 80°F in summer, prolonged exposure to extreme temperatures should be avoided.
- Pruning
The Tatarian Dogwood should be pruned to maintain its shape and encourage vibrant stem color, which is most notable in the winter months. The best time to prune is late winter or early spring before new growth starts. Prune about one-third of the oldest stems to the ground yearly, and trim out any broken, diseased, or crossing branches to maintain air circulation and plant health.

- Life cycle
Cornus alba 'Siberian Pearls,' commonly known as Tatarian dogwood, begins its life cycle with seed germination, generally occurring in spring as temperatures rise and daylight increases. After germination, the seedling grows through the vegetative stage, developing a root system and foliage during the growing season. As the plant matures, it enters a period of rapid growth, where both roots and stems extend, and the characteristic red bark develops. Following the establishment, the Tatarian dogwood enters the reproductive phase, producing clusters of white flowers by late spring or early summer, which then give way to clusters of white to pale blue berries, or drupes, by late summer or fall. As temperatures drop and days shorten in the autumn, the plant begins to enter dormancy; leaves turn to vibrant fall colors before dropping, with the plant conserving energy for the winter. With the arrival of the next spring, the cycle recommences, with new growth sprouting from the plant's established framework.

Propogation time
Late Winter-Early Spring
Cornus alba 'Siberian Pearls', commonly known as the Siberian Dogwood, can be propagated most effectively through hardwood cuttings. This method typically takes place during the plant's dormant season, which is late fall to early winter. To do so, select healthy, pencil-sized stems from the current year's growth and cut them to lengths of 6 to 8 inches (15 to 20 centimeters). Ensure each cutting has several buds. Dip the cut end in rooting hormone powder to encourage growth, then plant the cuttings in a mix of equal parts peat and perlite or sand, making sure at least two buds are buried beneath the soil surface. Place the cuttings in a cold frame or somewhere that has diffused light and ensure the medium remains moist but not waterlogged. Roots will develop over the winter months, and by spring, the cuttings can be potted up or planted out in their final location.
