Big Buckeye
Aesculus flava
A forest giant of the southern Appalachians, the yellow buckeye earns its scale with creamy spring panicles and foliage that holds its health through summer better than any of its relatives.
Yellow buckeye carries itself like the mountains it calls home: substantial, unhurried, and deep-rooted. Native to the southern Appalachians and occasionally the Piedmont of North Carolina, this deciduous tree reaches 60 feet in the lowlands and closer to 90 feet at elevation, developing a wide oval crown and a trunk that can exceed three feet across. In spring, six-inch upright panicles of creamy yellow flowers emerge above bold palmately compound leaves that unfurl earlier than most trees dare. The bark of older specimens begins to exfoliate in satisfying plates.
Unlike Ohio buckeye, yellow buckeye shows genuine resistance to the leaf scorch, blotch, and powdery mildew that plague the genus. It wants deep, rich, slightly acidic soil that stays moist but drains well — poor clay or dry ground will disappoint it. Its taproot makes it unforgiving of late transplanting, so site carefully from the start. Reserve this tree for parks, large naturalized areas, stream corridors, and woodland edges where its scale feels at home and its early spring bees are welcome.
