DECIDUOUS. Cornus alba sibirica, commonly known as the Red Stem Dogwood, is a deciduous shrub noted for its vibrant winter display. Its distinctive feature is its bright red stems, which provide a striking contrast against the snow. In spring, it produces clusters of small, white flowers that transition into small white berries. Siberian Dogwood typically reaches heights of 1.5 to 2 meters, making it an attractive and manageable addition to Australian landscapes with its colourful stems and seasonal interest.
