The Red Buckeye (Aesculus pavia) is one of the most striking spring-blooming understory trees native to the southeastern United States. Valued for its brilliant crimson tubular flowers and unique palmate leaves, it serves as a primary food source for early-season migratory hummingbirds.

1. Native Range & Identification

• Native Range: Southeastern and south-central United States, from coastal North Carolina down to Florida, west to Texas, and north into parts of the Ohio River valley.
• Leaves: Distinctly opposite, palmately compound leaves featuring 5 (rarely 7) finely-toothed leaflets radiating outward like fingers from a hand.
• Flowers: Showy, upright panicles of bright red to coral-pink tubular flowers that emerge in mid-spring, perfectly timed with the arrival of ruby-throated hummingbirds.
• Fruit: Smooth, rounded leathery capsules containing large, shiny brown seeds (buckeyes) rich in tannins. Note: Seeds and foliage are toxic if ingested by humans or pets.

2. Cultivation & Growing Requirements

Red buckeyes are remarkably hardy and adaptable, functioning well as large multi-stemmed shrubs or small trees reaching 10 to 20 feet in height.

• Sunlight: Performs best in partial shade to dappled woodland sunlight, though it tolerates full sun if provided with adequate moisture.
• Soil: Prefers rich, moist, well-draining loamy soils. It naturally populates river bottoms, rich woods, and ravine slopes.
• Moisture: Appreciates consistent soil moisture during the growing season. While established plants tolerate occasional dry spells, prolonged drought can cause premature summer leaf scorch.

3. Wildlife Benefits & Strategic Placement

• Pollinator Support: The tubular red blossoms are a magnet for hummingbirds, large native bees, and butterflies.
• Placement Tips: Plant along shaded wood-line borders, woodland gardens, or near patio viewing areas where you can easily observe visiting hummingbirds in early spring. Avoid heavy, baking dry clay unless amended heavily with organic matter.
