Multi-trunked tall shrub to medium-sized tree. The somewhat irregular crown becomes steadily broader until it is practically round. 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, measuring approx. 4 cm. They change colour from green to bronze and contain a few black seeds. The fruit remains on the tree for a long time. This tree prefers a sheltered site since young specimens can suffer frost damage, but recover well. Koelreuteria paniculata flowers more abundantly the warmer the summer. After flowering it produces triangular bladder-like fruits that contain the seeds.
