Korean Hill Cherry (Prunus serrulata var. pubescens) A small wild cherry with a broad, rounded crown, native to Korea, northeast China and Japan. The white to pale pink flowers are produced abundantly in early to mid April at the same time as the bronzy leaves emerge. Though small, the 5-petalled blossoms are accompanied by prominent red bud-scales, which add depth to the floral display. Trees can be recognized in spring by the sparse, downy hairs on the leaf undersides, flower stalks and new shoots.
