Aesculus glabra (Ohio buckeye): Leaves
The leaves are palmately compound and opposite, with 5 to 7 leaflets (usually 5). Each leaflet is 3 to 6 inches long and is finely toothed and gradually tapered at the apex and base. This is one of the first trees to leaf out in spring and one of the first to defoliate in autumn. Leaves are medium to dark green, turning yellow but sometimes a brilliant orange-red to reddish-brown in the fall.
