At first sight, Koelreuteria bipinnata looks very similar to the better-known K. paniculata. Yet there are the necessary differences. The annual twigs of K. bipinnata are up to three times thicker than those of K. paniculata. Also, the compound leaves are double to triple pinnate, where in K. paniculata they are pinnate to sometimes double pinnate. The leaves are unlobed in K. bipinnata. An important difference also shows itself after flowering; the bladder-shaped fruits of K. bipinnata are beautiful pink to pink-red. Unfortunately, this species can also spread easily, especially in warmer locations. The tree forms an irregularly rounded crown that later sags slightly. This makes K. bipinnata almost unsuitable as avenue tree. Quite apart from the fact that paving is not tolerated. Thanks to its good drought and heat tolerance, the tree does well as a solitary in sunny locations. In addition, the flowers attract very many bees.
Koelreuteria bipinnata can eventually reach a height of 9-12 m, depending on the site and climate conditions.
