RHS Plant Details
Description and Uses:

Cornus alba ‘Siberica’ is a medium (height 1.5-2.5m x spread 1.5-2.5m) deciduous shrub with a suckering habit. Left unpruned it can become a dense thicket. In gardens it is usually regularly coppiced to encourage the new stems that are bright crimson throughout the winter. The ovate leaves turn red-purple in the autumn, especially in sunnier aspects. Flowers are small and cream coloured, held in terminal clusters, whilst these are of limited ornamental value they are followed by bluish-white berries. The cultivar ‘Siberian Pearls’ is a particularly free-fruiting selection.

Cornus alba selections are valuable additions for winter interest providing colour from October to March.

Cultivation Requirements:

Grows in most conditions, in sun or partial shade.

Cut back hard annually (coppicing or stooling) before or just after bud break in March-April (pruning group 7) https://www.rhs.org.uk/advice/profile?pid=161

Feed with a general purpose fertiliser after pruning a water well in dry summers to ensure good regrowth.

Planting:

Plant bare-root transplants when dormant or container-grown plants at any time.

Problems:

Generally free from pests and diseases, seems to be resistant to cornus anthracnose.

Propagation:

Propagate by hardwood cuttings in a frame after leaf fall.
