Trees – Chinese Dogwood (Cornus Kousa var. chinensis)
Saturday, February 21st, 2009Cornus kousa var. chinensis was introduced from China in 1907 and differs from typical Cornus kousa in its taller, more open habit, usually forming a small tree. Despite having long-lasting pretty flowers, good autumn colour, an ability to blend well with other plants and a comparatively small size, the Chinese dogwood is not seen too often, even though it is easy to find in garden centres and nurseries.

The flowers are the most intriguing feature of this tree. They are very small and would be inconspicuous if it were not for the four white bracts (leaf-like attachments) that surround them. Because they are bracts, and not petals, they remain in flower for a very long time. They start white, but become flushed with pink as they age.
The leaves are a bright, fresh green colour, which sets off the flowers well. In autumn, they turn a wonderful range of oranges and reds. This tree is quite hardy and should survive most winters easily. Apart from removing any dead or damaged, wood, no pruning is required.
Growing Requirements
Soil
Cornus kousa var. chinensis is best grown as a specimen tree. It will grow well in a fertile, humus-rich, soil, located in full sun or partial shade. It is not recommended for growing in poor, shallow, chalk soils. It prefers an acid to neutral soil but can be grown in slightly alkaline conditions.
Size
The Chinese dogwood can grow to a height of 20ft (6m) and spread to around 15ft (4.5m), though in the average garden, 12ft to 15ft (3.5m to 4.5m) is the more likely ultimate height.
Propagation
It propagates well from seed, which should be cold stratified when ripe and then sown the following spring. It can also be propagated by taking cuttings in the summer.
Family: Cornaceae
Genus: Cornus
