About

Cornus kousa 'National' grows into a robust tree, reaching heights of up to 6 meters with a broad, vase-like form. The leaves are variegated, elliptical, and pointed, featuring wavy edges adorned with white splashes and green centers, transitioning to shades of orange and red-purple in the fall. In late spring to early summer, large, creamy bracts resembling petals emerge, enveloping small flower clusters and layering above the foliage. By autumn, this tree produces sizeable red fruits, measuring up to 4 centimeters across.
