Slow-growing cultivar with a remarkably narrow, column-shaped manner of growth. The large, pinnate (sometimes doubly pinnate) leaves consist of 7 - 15 leaf segments. These are approx. 7 - 10 cm long and the lobes have a serrated edge. The leaves are a bronze colour in the spring and turn yellow to orange in the autumn. The numerous small, yellow flowers are in terminal plumes approx. 30 cm long. The plumes are open and have a loose structure. After flowering, the bladder-like fruit appear, approx. 4 cm in size. They change colour from green to bronze and contain a few black seeds. The fruit remains on the tree for a long time. The 'Fastigiata' flowers are nothing like as numerous as those of the species. Should be planted in a sheltered spot since young trees can suffer from frost damage. They do, however, recover well.
