Japanese Cornel dogwood (Cornus officianalis) is a separate dogwood species from Cornelian cherry dogwood (Cornus mas), but shares many of the same characteristics -- abundant yellow flowers in late winter/early spring, red fruit and exfoliating bark. The Spring Queen cultivar was selected by the Klehm nursery for its abundant spring blooms.

Members of the genus Cornus, commonly known as dogwoods, are welcome in the home garden for their multi-season interest -- be it flowers, fruit, foliage, and/or bark -- and their range of forms from small trees to suckering shrubs. The dominant display, however, varies among the species.

Dogwoods are native to cooler temperate areas of North America and Asia. The genus includes 45-60 species, divided into subgenera about which taxonomists disagree. The Chicago Botanic Garden's collection includes almost 100 varieties of dogwood from 20 species (7 of which are native) and over 2,400 plants.
