TREES FROM ASIA
The genus Koelreuteria comprises three species of woody plants in the sapindaceae (soapberry) family. They originated from East Asia. A golden rain tree, Koelreuteria paniculata, can be viewed at the Karlsruhe Botanical Gardens. It is also known as the China tree. Its leaves are similar to those of an ash tree and turn stunning shades of yellow and orange in the fall. In July and August, it develops 40 cm long loose branching clusters of yellow flowers.
