City Slicker River Birch

City Slicker River Birch (Betula nigra 'Whit XXV')

City Slicker River Birch (Betula nigra 'Whit XXV') is a refined, urban-adapted cultivar of the native river birch, valued for its bright exfoliating bark, upright form, and strong tolerance to city conditions. Bred for heat tolerance and mildew resistance, this tree is a dependable performer in both residential landscapes and civic plantings where toughness meets ornamental appeal. The bark peels in shades of creamy white, tan, and salmon-pink, offering standout winter interest.

Distinctive Features

City Slicker River Birch matures at 35 to 45 feet tall with a spread of 25 to 30 feet, forming a graceful, upright crown with strong central branching. The bark is lighter and smoother than many other river birch selections, giving it a striking appearance in all seasons. Its dark green leaves remain clean and vibrant through the summer, turning a soft golden yellow in fall. Selected for improved resistance to leaf spot and adaptability to heat, it is especially well suited for southern and urban climates.

Growing Conditions

• Sun Exposure: Full sun is ideal, but it tolerates partial shade.
• Soil: Performs best in moist, acidic, well-drained soils but is tolerant of clay and urban conditions.
• Water: Moderate to high; prefers moist conditions but tolerates short dry periods once established.
• Humidity: Excellent mildew resistance in humid southern regions.
• USDA Hardiness Zones: 4�9; one of the most adaptable birch cultivars for a wide range of climates.

Ideal Uses
