A small deciduous tree with showy flowers. The Buckeye has an unusual adaptation to extreme climate during the hot rainless summer months by dropping its leaves mid-summer.  Large  fragrant rosy flowers are sometimes still on the tree when this happens making a remarkable statement in the landscape.  New foliage appears apple green in late winter and mature leaves are a rich green  giving way to some fall color.  The large fruits of this tree are poisonous and slowly ripen and fall when it rains.  They can be grown into small plants the way avocado seeds are grown in glass jars.  These fruits are not dispersed by wind or birds but roll downhill  possibly into running water  which carries them to a new site. Indigenous americans threw seeds into ponds to stupefy fish which then rose to the surface and were easily caught. Interestingly  they would also grind the seeds  leach with boiling water  and use the flour as an emergency food source.
