An American cultivar with a narrow, vertical, conical to oval crown. Remains slightly narrower than 'Chanticleer'. Height 8 to 12 m. Compact manner of growth. Old bark is rough and greyish brown. The healthy, glossy green leaves turn lovely colours in the autumn, usually yellow, but also purplish red tints. Remain on the tree until late in the autumn. Profuse flowers. The white flowers grow in umbels of 6 to 12. Each flower is approx. 2.5 cm in diameter and is thus somewhat larger than the flowers of 'Bradford' for example. The fruit is brown with lighter lenticels and appears rarely. Suitable as a solitary tree and along narrow avenues and streets. Deep root system. Prefers neutral to slightly calcareous soil. Also grows in poor soil. Well resistant to air pollution.
