Abstract

An interspecific hybrid of Cornus kousa×C. nuttallii exhibits the vigorous nature and the floral display of large, white bracts of plants of C. nuttallii and the dark, glossy green foliage and disease and insect resistance of plants of C. kousa. The hybrid thus provides a new, unique, and superior large-bracted dogwood for landscaping purposes. Plants of C. nuttallii become very large in nature in areas where they are indigenous but seldom thrive in other areas. Plants of this novel hybrid are expected to thrive in many regions of the world where plants of C. kousa perform well.
