Description

A superb, unusual large shrub with silver variegated leaves and a striking, tabulated habit. In summer, pretty clusters of white flowers appear, sitting on the upper surface of the tiered branches and contrasting beautifully with the variegated leaves. The unique shape only becomes apparent after several years growth.

Cornus alternifolia 'Argentea' is a stunning, architectural garden plant ideal for a sunny position with a little space!

Supplied Size: 3L containers

• Position: Full sun or light, dappled shade.
• Soil: Any fertile soil.
• Hardiness: Hardy
• Flowering Period: June.
• Flower Colour: White
• Rate of Growth: Slow to moderate.
• Habit: Cornus alternifolia 'Argentea' grows to be a large shrub with a handsome tiered shape once established.
  • Height: 3 m (10 ft)
  • Spread: 2.5 m. (8 ft)

• Pruning: After planting, look for a strongly growing stem developing after about two to four years, perhaps growing at an odd angle but obviously much more vigorous than the normal shoots. Train this stem vertically (usually up a thin bamboo cane or similar) to form the trunk and basis of the tiered structure.

• Some plants occasionally produce two or even three of these vigorous "leaders", in this case remove all but the most central one. Once established we find a new tier of branches develop every four years or so.
