| Huge, vigorous deciduous tree. Compound leaves are medium green with a herringbone pattern. Small white flowers with pink markings bloom in late spring in erect conical clusters of a few dozen flowers each. Flowers are followed by the tree's distinctive spiny fruit, with a large chestnut found in each one. Provides heavy shade and requires ample summer water. 'Baumannii' has double flowers and does not set seeds. |
