Autumn Splendor Buckeye

Autumn Splendor Buckeye (Aesculus � arnoldiana 'Autumn Splendor')

Autumn Splendor Buckeye (Aesculus � arnoldiana 'Autumn Splendor') is a hybrid shade tree known for its large upright panicles of pink-red spring flowers, glossy disease-resistant foliage, and vibrant fall color. A cross between Red Buckeye and Ohio Buckeye, this cultivar combines ornamental beauty with strong landscape performance. Its moderate size, symmetrical shape, and multi-season appeal make it a valuable focal point or shade tree for residential and public spaces alike.

Distinctive Features

'Autumn Splendor' typically matures at 35 to 45 feet tall and about 30 to 40 feet wide, forming a broad, rounded crown. In mid-spring, it produces upright clusters of rosy red flowers that attract hummingbirds and pollinators. The dark green foliage is composed of palmate leaflets with a lustrous sheen, remaining attractive throughout summer and turning fiery orange to red in fall. Unlike other buckeyes, this selection is highly resistant to leaf scorch and leaf blotch, keeping its foliage clean well into the season.
