Chestnut Oak

Chestnut Oak (Quercus prinus)

Chestnut Oak (Quercus prinus), also known as Rock Oak or Mountain Chestnut Oak, is a rugged deciduous tree native to the Appalachian Mountains and eastern U.S. woodlands. It is valued for its deeply furrowed bark, tolerance of rocky, dry soils, and glossy foliage that resembles that of American chestnut.

Distinctive Features

Chestnut Oak typically reaches 50 to 70 feet tall with a broad, rounded canopy. Its coarsely toothed, oblong leaves are shiny and dark green, turning golden-yellow to orange-brown in fall. The bark is thick, deeply ridged, and dark gray�often used as a distinguishing feature among eastern oaks. Acorns are large and sweet, ripening in early fall and serving as a key food source for wildlife.

Growing Conditions

• Sun Exposure: Full sun to partial shade
• Soil Type: Dry, rocky, or sandy soils; excellent on slopes and ridges
• Soil pH: Acidic to neutral
• Water Needs: Low to moderate; very drought-tolerant once established
• USDA Hardiness Zones: 4 to 8

Ideal Uses

• Focal point for rugged hillsides or naturalized spaces
• Shade tree for large residential lots or parkland
• Native woodland restoration or reforestation projects
• Dry slope or rocky outcrop stabilization
• Wildlife planting for deer, turkey, and small mammals

Low Maintenance Care

• Prune in early years to establish strong branching structure
• Mulch base to support moisture retention and root health
• Requires minimal supplemental water once established
• Rarely troubled by pests or major disease problems
• Tolerates harsh conditions and poor soils with ease

Why Choose Chestnut Oak

• Excellent drought resistance and rocky soil tolerance
• Distinctive bark and foliage offer year-round interest
• Supports wildlife with abundant, nutritious acorns
• Adaptable to challenging terrain and exposed sites
• A strong, enduring focal point for rugged landscapes

Chestnut Oak thrives where many trees fail, offering strength, longevity, and ecological value�making it a standout focal point for dry slopes, upland woods, and naturalistic designs.
