Cornus kousa

 

Japanese dogwood

Cornus is commonly known as dogwood, the varieties of which can be distinguished by their blossoms, berries, and bark. They are deciduous trees or shrubs, but a few species are perennial sub-shrubs, and some of the woody types are evergreen. Several varieties produce inconspicuous flowers. Cornus kousa is a small deciduous tree to12m tall and is widely cultivated as an ornamental flowering dogwood.

Cornus kousa

Cornus is commonly known as dogwood, the varieties of which can be distinguished by their blossoms, berries, and bark. They are deciduous trees or shrubs, but a few species are perennial sub-shrubs, and some of the woody types are evergreen. Several varieties produce inconspicuous flowers. Cornus kousa is a small deciduous tree to12m tall and is widely cultivated as an ornamental flowering dogwood.


Planting

From Late Winter TO Early Spring

Shrubby dogwoods grown for their winter stem colour (Cornus alba, C. sericea and C. sanguinea cvs.) are unfussy about their soil conditions, but they are able to thrive in damp conditions where other shrubs might fail. C. controversa (the wedding cake tree), C. alternifolia (the pagoda dogwood), C. mas (the cornelian cherry) and C. officinalis are also tolerant of a range of soil conditions. Flowering dogwoods Cornus florida, C. kousa, C. capitata and C. nuttallii do best in well-drained but fertile soil that is rich in organic matter and neutral to acid in pH. C. kousa (from Korea and Japan), is more tolerant of neutral to alkaline conditions than are the North American species C. florida and C. nuttallii. All Cornus species will tolerate full sun or partial shade, but those grown for their winter stem colour show better colour when grown in full sun.

 

Propagation

From Mid Spring TO Early Summer

Species plants can be propagated from seed, but named cultivars will not come true to type from seed and are better propagated from hardwood or greenwood cuttings. Variegated cultivars of C. controversa (the wedding cake tree) and C. alternifolia (the pagoda dogwood) are usually grafted commercially in winter, but may also be propagated at home from cuttings.
