The Ohio buckeye tree or Aesculus glabra, here being identified by PlantSnap.com, has "large spikes of green-yellow flowers in spring bloom at the same time the bright green leaves unfurl. This is one of the first trees to leaf out and also one of the first to lose its leaves in the fall. Summer leaf color is dark green and fall color is often orange-red" says GrowNative.org. | PlantSnap
