Yellow Buckeye - Aesculus flava
Potentially large, Yellow Buckeye is the tallest of the native buckeyes, reaching 90 feet in height. As with the other buckeyes, this species bears palmately-compound leaves. The individual leaflets are up to 8 inches in length, pointed, and toothed. Autumn color is yellow to orange. The showy yellow flowers are arranged in a panicle, and the husk of the large casule is pale, with dark brown seeds contained within. Limited in distribution, Yellow Buckeye is most common in the Tennessee and North Carolina mountains where it inhabits bottomlands, valleys, and slopes.
