Is an upright-branched ornamental tree. It grows pyramidal to columnar in youth, but tends to become oval to spreading with age. It is noted for its early profuse spring bloom, quality glossy green foliage and often excellent fall color. Shoots on species plants are thorny, but some cultivars are thornless. It produces small, inedible, greenish-yellow fruits (to 1/2” diameter) which are of little practical value or ornamental interest.
