Autumn Splendor Buckeye

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

Autumn Splendor Buckeye is a small to medium shade tree that earns attention with clean summer foliage and a strong red fall finish. It brings a classic buckeye look without the chronic leaf scorch that makes many Aesculus trees look tired by midsummer. The canopy provides comfortable, dappled shade that works well near patios and lawns. Plant it as a long-term landscape feature when you want dependable structure with a reliable autumn payoff.

Distinctive Features

This hybrid buckeye is valued for glossy, dark green leaves that hold up well through summer, followed by deep maroon to red fall color. In late spring, upright flower panicles open in yellow tones, often with warmer reddish accents, adding a soft seasonal highlight. The tree develops a dense, rounded to oval canopy with a sturdy, refined outline that reads well as a specimen. It may produce buckeye nuts after flowering, which add some seasonal interest but should not be considered edible.

Growing Conditions

• Sun: Full sun to partial shade, with best color and strongest growth in full sun.
• Soil: Average to fertile, well-drained soil, adaptable to a range of soils when drainage is reasonable.
• Water: Medium, keep evenly moist during establishment, then water during extended dry periods.
• USDA Zones: 4 to 7.
• Mature Size: About 25 to 35 feet tall and 20 to 30 feet wide.
• Habit: Upright when young, maturing to an oval to rounded canopy.
• Foliage: Glossy dark green in summer, turning maroon to red in fall.
• Flowers: Yellow flower panicles in late spring.

Ideal Uses

• Focal Point: Plant as a specimen where the clean summer canopy and deep red fall color can anchor a main view.
• Small Shade Tree: Provides comfortable, dappled shade for patios, lawns, and outdoor living spaces.
• Street Tree: A strong option for residential streetscapes where a durable, medium-sized canopy is needed.
• Front Yard Structure: Adds an orderly canopy and strong seasonal color without overwhelming the house.
• Mixed Borders: Use behind shrubs and perennials to add height, texture, and a reliable autumn finish.

Low Maintenance Care

• Pruning: Prune in late winter to develop strong branching and remove crossing or damaged limbs.
• Watering: Deep water through the first one to two growing seasons to establish a resilient root system.
• Mulching: Mulch over the root zone to conserve moisture and moderate soil temperatures, keeping mulch off the trunk.
• Feeding: Feed lightly in spring if needed, and avoid heavy fertilizing that can push weak growth.
• Fruit Awareness: Site thoughtfully if nut drop is a concern, and keep nuts away from pets and children.
