CORNUS KOUSA AND ITS PROPAGATION
Alfred J. Fordham
Cornus kousa, the Kousa dogwood, is one of the most outstanding and trouble-free small trees available to horticulture. It is indigenous to Japan, Korea, and China and is hardier than our native C. florida.

Other features include its month-long floral display, its attractive fruits, its autumn color, and its mottled, exfloliating bark, which is prominent on trunks and branches of older plants.
When plants are raised from seeds, seedlings grown from some plants duplicate one another with monotonous uniformity. Seedlings of other plants, however, may contain individuals which differ greatly from other members in the same lot. Such variation can lead to new and worthwhile selections with horticultural merit.
Both C. kousa and C. florida provide striking examples of the variation that can arise when plants are raised from seeds. They can show great variability in all respects —
