Noteworthy Characteristics:
Native to China, Japan and Korea, Cornus officinalis (Japanese cornel dogwood) usually grows as a large, spreading, multi-stemmed, deciduous shrub to 15-25?tall. It also may be grown as a small tree. It is very similar to Cornus mas (see C290), except it grows with a slightly more open habit, flowers one week earlier, has more attractive bark and often has brown hair tufts in the vein axils on the leaf undersides. Ovate to elliptic, dark green leaves (to 4 3/4?long). Variable fall color ranges from drab pale yellow to attractive reddish-purple. Yellow flowers appear in late winter to very early spring before the leaves in 3/4?wide clusters (umbels). Flowers are followed in fall by oblong red fruits (drupes) that are technically edible but astringent. Exfoliating bark has tones of gray and brown.
Problems:
No serious insect or disease problems.
Uses:
Effective in foundations, shrub borders, woodland gardens, bird gardens or naturalized areas. Grow as a hedge. Train as a small tree.
