Ruby Red Horse Chestnut

Ruby Red Horse Chestnut (Aesculus �carnea 'Briotii')

Ruby Red Horse Chestnut (Aesculus �carnea 'Briotii') is a hybrid flowering tree prized for its vivid rose-red flower spikes, dark green foliage, and compact, rounded habit. A cross between red buckeye and common horse chestnut, this cultivar brings the best of both parents: improved disease resistance, vibrant blooms, and a more manageable size. It's a standout spring feature in both residential and civic landscapes, with ornamental and structural value throughout the growing season.

Distinctive Features

'Briotii' typically grows 30 to 40 feet tall and 25 to 35 feet wide, forming a symmetrical, rounded canopy. In late spring, it produces large, upright panicles of bright pink to deep red flowers, often reaching 6 to 8 inches tall. These showy blooms attract bees, hummingbirds, and other pollinators. The foliage is a glossy, deep green, composed of palmate compound leaves that remain clean and attractive through summer. Unlike the larger Aesculus hippocastanum, 'Briotii' rarely drops unsightly fruit, making it better suited for lawn or street-side use.

Growing Conditions

• Sun Exposure: Full sun to light shade; best flowering in full sun.
• Soil: Prefers moist, well-drained soils rich in organic matter; tolerates clay and loam.
• Water: Moderate; appreciates regular moisture during dry spells, especially when young.
• Humidity: Performs well in temperate and humid climates with good air circulation.
• USDA Hardiness Zones: 5�8; hardy and dependable in much of the eastern and central U.S.

Ideal Uses

• Focal Point Tree: Eye-catching spring flowers and refined shape make it an ideal landscape centerpiece.
• Residential Lawns: Moderate size and tidy habit are well suited to front yards or estate plantings.
• Street or Boulevard Plantings: Non-invasive roots and minimal fruit drop make it a good urban tree.
• Public Gardens and Parks: Seasonal interest and pollinator support enhance open spaces.
• Educational or Historic Landscapes: Offers traditional charm and long-lived structure.

Low Maintenance Care

Ruby Red Horse Chestnut is an easy-care tree when sited properly. It benefits from consistent watering during establishment and seasonal cleanup, but otherwise requires little intervention.

• Watering: Deep, regular watering is important during the first few years; mature trees are moderately drought tolerant.
• Pruning: Prune in late winter to remove crossing branches or shape the canopy; minimal pruning needed once mature.
• Fertilizing: Apply compost or a balanced fertilizer in early spring, especially in poor soils.
• Pest and Disease Resistance: More resistant to leaf scorch and fungal issues than common horse chestnut.
• Winter Care: Fully hardy; mulch around base in fall for root protection in exposed sites.
